My favourite pizza in London for the last 5 years. It’s inexpensive, quick, and very rarely have I had a poor bite in dozens of visits. You order at the front, get a buzzer, and it’s usually ready within 10 minutes from ordering. Seating is tables of 4-8 stools each, often sharing with other groups. Toilets and tables are almost always clean, and service prompt. The only slight downside is it can be a big loud to have a conversation but honestly just go for the pizza anyhow!

The place was so chill and spacious close to King cross. They have multiple locations. They offer delivery,pick up and dine in. We ordered Funghi Pizza, Fiorentina, and Formaggi and their dip. It was enough for 5 people. The Formaggi was the best Pizza in London! You need to eat here cheap yet the quality is outstanding. Highly recommended! Would definitely come back.

The pizza here tastes very similar to how pizza tastes in Italy. As soon as you walk into the restaurant you get that beautiful aroma of freshly baked pizza. We ordered the Funghi Pizza and added an extra topping of onions. Then, as I liked it so much, we got another one (just a plain Margarita) with onions as extra topping. The tomato base was just yum! The cheese was fresh too! you could tell that the mozzarella was good quality. The crust was crispy and the base was thin. The staff were friendly too. We also got the hot sauce and a tub of pistachio ice cream. The prices were very reasonable considering the location and the service was prompt and speedy. Overall a great place to enjoy authentic pizza. My only comment would just be that it would be great to have some halal options in the menu!

Tolles Pizza Restaurant mit modernem und schnellem Konzept. Die Pizza war aber nichts aussergewöhnliches. Ganz OK. Sehr preiswert.

Cool place to meet friends, eat pizza and drink a bottle of beer. Location on a thoroughfare street. Large room and enough space, pleasant atmosphere, dim light and warmth from candles. The pizza is delicious, you can add extra sauces to it. There are warm and cold drinks.

Great value for money! Found this place late on Tuesday evening when looking for a quick meal. We ordered Papperoni and Formaggio pizzas - both ready super quickly. The crust is really thin and crispy. Pizzas tasted great. The staff and atmosphere were really chill. I'd recommend.

Great start to our holidays. Stayed the night in London and found this lovely gold mine of a restaurant. Staff gave excellent service and the food was absolutely amazing. Highly recommended to anyone passing through this area.

What a great place! All the pizzas are 12 inch. Personal or if your like me sharable with one person. Add the olives, breadsticks and a beer and I am good! They have this hot chili oil you can add on your pizza to spice it up! All pizzas are thin crust, made to order and out fast. Loved those place!

After perhaps being a tad intoxicated, what is a better way to continue your afternoon? Pizza and frozen cocktails of course! The venue is not far from Kings X Station and is a large spacious area. Neón lights give it that trendy and hip edge. As you enter there wasn’t anyone to let us know if we just find a seat or if we needed to be seated so, we kinda floundered our way to a table. You order at the till, take a buzzer and you are alerted to collect your creation. No pizza is more than £7.00! Lots of option and customisable is required. Pizza came very quick and was eaten just as fast. Super thin crust. Good amount of toppings. Boom. Decent choice of drinks (Frozen Margs, Mojitos, soft drinks and beers) and little starters such as olives and breadstick things. Garlic/Chilli Dip. £0.55. Game. Changer. Friendly staff and a great atmosphere and I will definitely be back! Finally, there is Wifi. It’s free.

Wow! What a fantastic experience for an affordable price. I would recommend anyone come here even if you are not near kings cross. The pizza is well baked, packed with wonderful flavors and definitely worth the price on the menu. The salad is pretty bitter so if you’re not a fan of that you may want to stay away from it. But definitely get some pizza from this place, you won’t be disappointed!

Nice pizza bar. Good concept for quick turnaround and bite on the go. Very reasonably priced and tasty. Margherita is under £6 which is quite amazing for London. Pizza is 12" thin crispy crust but don't expect Neapolitana with fior di latte mozzarella and San maranzano tomatoes. Quick service, tasty pizza from wood fire oven makes it well worth a visit. It's only 5 minutes walk from King's X station. I'll be back.

A lovely experience. The staff were helpful and friendly. The pizza was delicious and reasonably priced. When we went, it was busy and noisy. That is my only thing I could find fault with. We have to go to London next month and we will use it again.

Been several times. Consistently very good pizza: never burned, very fast. It's usually busy, but there are a couple of free tables. Recently, my favourite pizza place. The selection in the menu is good

Good for a quick bite. The Pizza is made very quickly and tastes fine. It was not the best pizza, but I would not expect it for the good price. The atmosphere is good and the service is friendly. I would recommend it if you need a good and quick meal.

Lunch at Pizza Union, a delicious pizza, fantastic price, trendy restaurant and a short walk from Kings Cross/ St Pancras. You collect the order, I went for the Tropicali (aka Hawaiian) and it was delicious 😋 What's not to love.

Great portions, fast, cheap but can add up if you get drinks and all. However does the trick! thin crispy pizza and a must for students!

One of the best pizzas I've had in london.... And ive tried alot. Make sure to get the egg on top of whatever toppinga you get. Customise your pizza to yojr liking and suoer reasonable price.

Nice pizzas, they've got good thin bases but not super full with toppings (I like a lot). Reasonable price, especially for a London place. Always really quick for eat in or takeaway. One or two salads on the menu as well. I think between £5.95 (margarita) and £8.50 (vegan toppings) for a pizza. £2.50 for gluten free dough.

Visited PIzza Union afer a football match that left with a growling belly and fancied a quick snack. Opted for the CALABRIA pizza with Nduja Spicy Sausage. The thin crust was like a crispy, edible trophy, and the Nduja sausage brought the heat, washed down with a glass of house red. If I find myself back in the area, I will be heading in their direction again for sure!

Love this place. Super simple, quick but really very tasty pizza at an incredible price. Fancy a tasty, cheap, quick bite in London? You don't get better than this.

This was an excellent pizza for the price and very affordable. I was surprised there weren't more meat options, but it was still very tasty. Crust is quite thin but still has a nice slightly flaky texture to it. I ended up getting the Calabria and it was a perfect amount for lunch, I was quite full after! Ambiance is nice and plenty of seating. Walls were a bit dirty but it adds to the industrial vibes of the place 😄

I love this restaurant because Ahmed works here and he has a beautiful smile. Thank you

Really nice pizza’s. Employees are very friendly and are laughing with eachother with is a good thing. The pizza’s are crispy and delicious!!!! Thankyou for having us in our london trip vacation.

Pizza Union is the one of the best cheap eats in London. It's reliably great every time. Super thin crispy base, plenty of toppings and not over-laden with cheese. I can never usually finish a pizza but these are light and the perfect size. Two people can eat and drink for £20. Plus great frozen cocktails for £3.50!? Can't go wrong.

Tremendous pizza, freshly made, quick service and nice surroundings. Amazing prices for Central London, totally recommend.

Excellent quality/price pizzas. Quick service , nice ingredientes , thin and tasty dough . Plenty of space to seat around .

Very very fast service. The pizzas are thin crust and what we ordered were delicious. Reasonable price.

I have ordered the following: 1- Margarita Pizza 2- Pollo Pizza Both were delicious but the Margarita was amazing! The prices was more than reasonable. Highly deserve the high rating with their quality and prices. Fur sure it will be my first pizza option in London.

If you’re looking for good value and good quality pizza union is the perfect place. Our pizzas were ready in 10 minutes, they were fresh and hot, the base is a bit thin and crispy. Garlic dip is so good and creamy. Frozen raspberry mojito was okay, nothing special about it.

Ordered online for a click and collect takeaway order. It was ready on time for collection. The pizzas were delicious the base was crispy and we'll cooked. The ingredients were all very fresh. They even cut the florintina so the egg didn't get broken. So much attention to detail. Definitely recommend

Great pizza at great prices! I often pop in here for many different occasions to make the most of the quick and easy service, getting a pizza for a fiver in London is almost impossible, getting a good pizza at this price even harder! I had the Regina pizza that comes with ham mushrooms and olives, all fresh ingredients in a wood stove oven, what a place! Thanks pizza union

Very surprised to find a reasonably price restaurant in London that offers tasty wood fired pizza. We went at around 8:15pm on a Wednesday and the place was hopping, nice and busy, with a great casual vibe. Service was quick and friendly, and pizza was delicious. Will definitely visit again next time I’m in LDN.

Everything was amazing! Our food came out so quickly, the pizzas had so much flavour. They were really filling so couldn't finish it all. Of course we asked for a takeaway box to finish it on the way home 😁 the staff were absolutely lovely, always made sure we were looked after and had everything we need. We definitely will be visiting again on our trips to London

Wow! What a fantastic experience for an affordable price. I would recommend anyone come here even if you are not near kings cross. The pizza is well baked, packed with wonderful flavors and definitely worth the price on the menu. The salad is pretty bitter so if you’re not a fan of that you may want to stay away from it. But definitely get some pizza from this place, you won’t be disappointed!

Atmosphere is nice and unique like a pub. There are various menus and price is reasonable. Salad is very fresh. We could enjoy a meal.

found this place through restaurantinlondon.co.uk - and oh my was it wonderful. had a mushroom pizza. something like £5. RIDICULOUS. now my go to whenever i'm around kings cross. would highly recommend!

Pizza's are wonderful. Thin crust also. Cooked on the stone oven, which give that little crisp to the edges. Prices are really good. You can't complain at £6.00 for a pizza in the centre of London. Would definitely recommend.

Amazing service, staff very friendly . Came and with couple of friends and we really love the pizza . Staff were so friendly and professional and we got to know their names Adriano, Adrian Luca and Laura . We will be back

One of my favourite places to eat at and regularly visited during lunch breaks. Prices are very cheap considering the area (£6 a pizza!!). The pizza’s are made very quickly, service is excellent and they taste great - what more could you want!
