Solid flat whites every time I order here. And great service too! I stepped in right before closing time when they were just closing the till, but the barista was so friendly to serve me when I imagine they must’ve had a busy day.

Great coffee and ambience. Absolutely love their limited edition blends, which are always unique.

Great coffee place, got two branches within 5 mins walk from each other. Good coffee, nice service and awesome pastries. Wish there were more hot breakfast options, menu is pretty slim

One of the best cafes in central London. The coffee is deep, varied, and offered by knowledgeable staff. Comes with a good bakery range. Bright and minimalist interior.

v lovely place with lovely people; real coziness comes in "do you want to stay with us or take away?" So I decided to stay and enjoyed my banana bread and ice chocolate. :)

Slightly off Oxford Street, so you may miss it if you stick to the main road, but I'm very glad we wandered slightly away from the bustling crowd, as this was a real gem. It's on a side street, so much more quiet. We found a seat straight away by the window. The coffee was superb and the food came quickly, was hot and tasted lovely. Staff were friendly and enthusiastic. Would recommend a pit stop in here if you're shopping on Oxford Street.

Excellent coffee! Had the iced skinny latte, which was awesome! Deserves its great reputation

This is the BEST cappuccino I had in London (I rate coffee places). So so good, their latte is also incredible! Great ambiance and staff is also super friendly!

Great second location of Kaffeine coffee shop. Came in a busy morning, there was not a lot of space but great atmosphere. The coffee was as expected, excellent and well balanced. Cannot recommend more. Great location, definitely come if you work in the area. Staff are absolutely excellent. Follow me on Google Maps for more coffee reviews

Called in for Brunch this morning, I visit Kaffeine every time I come to London. We love the coffee, the quality and selection of food and the service is excellent. The set up is in my opinion the benchmark for independent coffee shops everywhere. Professional, knowledgeable, polite, smiling staff in a clean and practical environment, serving excellent coffee and fresh produce. I see the owner Peter, helping out, serving coffee, cleaning tables and interacting with his staff and numerous customers. There is a steady stream of regular customers, who know exactly where the best cafe in London is.

Best coffee in the city, few chooses for breakfast but amazing ones. Cute place and welcoming.

Had the quiche and salad combo and it tasted delicious (so many vegetables and flavours) followed by an excellent cappuccino. Service was super quick and friendly - there were always many people coming in but everyone got their coffees and food very quickly - and it really seemed that the staff knows what they are doing. Can’t wait to return.

Good location, well priced coffee and helpful staff. Service was quick even when very busy (I just had coffee so can't comment on food). I had a batch brew filter and it was very under extracted, sadly. I maybe should have said something at the time but I had to get somewhere else quite quickly. Wouldn't rush back. There are other great third wave coffee shops very close by.

Nice place with good coffee. The atmosphere is a little less fantastic

Easily one of the best Oat Flat whites I have had. Great quality! All the cakes looked delish too. Very nice vibe and some seating outside as well. Def coming back.

Chill atmosphere here. It’s a very cozy coffee shop. They have nice coffee beans. We enjoyed our coffee and they offer us filtered coffee to try which they will sale next week. The filter coffee was nice too.

Very clinical set up. Good food selection and a great place to spend a few hours. Coffee - 8.0: they use an interesting bean choice which offers a different taste. Slightly sweet but with enough floral notes to keep it honest. Very enjoyable. Milk work was very flat but smoothly mixed.

Nice coffee, the pattern on the coffee is very nice too., I had an espresso and chocolate cookie which was tasty. Seatings are cosy and comfortable, there is a jug of water you can get it yourself, but a waitress was taking some to our table which is very nice of her. Overall a very pleasant experience.

The coffee tasting flight was delicious - this place is the epitome of specialty coffee. And amazing service by knowledgeable and friendly staff.

A great coffee shop just north of Oxford Street. The black coffee is great, not too bitter like some places. Chocolate brownies are amazing. Staff are friendly and attentive. Will always pop in if nearby.

Fantastic staff, amazing coffee , perfect location and clean all round. One really couldn’t ask for more from a coffee shop. I recommend the flat white and the bacon brioche. Thanks Kaffeine!

Very tasty and unique flavoured coffee. Ordered banana bread - asked if I'd like it 'toasted with butter'? Erm yes please. Not disappointed...

Excellent coffee, served with a tea palette cleanser. Staff is knowledgeable and extremely nice. Space is smart, cozy, and modern. Even the food is surprisingly varied for such a small place. Absolute gem!
