My friend and I ordered a 24" half cheese half pepperoni pizza. We were excited for the novelty of such a large pizza, but alas.. our hopes were dashed when we got home and found short, dark, curly hairs baked into the cheese. We called to get a refund, and the person on the phone was incredibly unapologetic and rude. When we returned to the store to get the cash refund, we noticed the man making pizzas had a bushy beard, and wasn't wearing a hairnet over his beard. I will never go back, and suggest that you avoid this place if you like your food hair-free.

Ordered pizza at 5:48 pm. Did not receive pizza until 7:30 pm. Had to call twice to get it delivered. Then couldn't eat the $8 salad, because it was full of black, slimy greens. Pictures below. I wrote about this on their Facebook page last night, and they have since deleted it.

Loved that I could create my own pizza via the app; down to which half the toppings were on and how to cook and cut it. The pizza arrived earlier than the estimated time (on a snowy night, no less), plus you can't beat free delivery. The delivery driver was friendly, calling first to let me know he was here and ask about the best entrance. Bonus: I got coupons for my next order with the delivery. Everything was prepared and cooked exactly as ordered and very delicious. Will definitely be ordering from here again in the future!

How on earth did I let myself pay near $12 for 2 slices of pizza? It was trash, dried out, nearly flavorless. I couldn’t even finish eating the 2nd slice. The staff moves at 1/2 speed, they don’t seem to understand that people value their time as much as their money. My experience in this farcical charade pretending to be a pizzeria needs a wake up call, cooks that know how to make a decent pizza and a counter person that isn’t an airhead. I don’t feel one ounce of bad for sharing this opinion. Next time in Boulder, I’m sticking to Tacos, this place ruined Pizza for the entire city.

Really tough to spend nearly a half hour in this place just trying to get two slices that I picked from ones that were already prepared in the window. Place wasn't busy at all, maybe 2 or 3 other customers. The employee truly just gave me the one slice hoping I wouldn't notice being shorted a slice and a spicy ranch. I had to ask for the pizza I had already paid for. What a joke

My fav place for Pizza slice while I was in Boulder. 2 pizza slices for about 9$.

First of all. Where’s Wanda?!? This pizza is amazing. I suggest to add a few toppings to the pizza behind the glass, only 50¢ per. The upmost friend staff. Kai is amazing and deserves a tip just for his great conversation while your pizza is cooking. Best quick pizza place around

Excellent and quick. The pizza slice is huge, hot, and delicious. Customer service was wonderful. Prices are reasonable. This establishment is clean as well as the bathroom. Recommend this location.

Our order took 2hrs to deliver after we called at the hour mark - they gave us the excuse it was a busy game day - after 2 hours we finally got the pizza! Manage expectations if it's going to take 2 hrs tell folks and maybe give them the option to pick-up.

Good cheap slice of pizza and their spicy ranch is AMAZING. I moved out of boulder a while ago and have always been trying to get their ranch, but they now can it, so I can bring it back home, wohoo!

Usually love a slice from Cosmos, but today I ordered a slice of mushroom and got a total of 3 wafer thin pieces of topping and a few crumbs. Bummer.

I had the 2 slice and a drink lunch special, which was a very good deal and was pleasantly surprised at the size of the slices. They are huge! I have had a lot of actual NYC pizza in NYC and this was very authentic and quite tasty. Service was friendly and quick. I will definitely come back and I definitely recommend Cosmo's for an authentic NY pie.

Edit: I order online and noticed the 1 free topping is not free. I don't know how long this has been going on. It may only be a couple dollars per pizza but that doesn't change the reality that this is false advertising. One star for good food and service. You got two because 0 isn't an option. Never in my life did I think pizza would break my heart. Origional: Great pizza and delivery has always been quick for me.

Stopped in for a quick slice. Friendly staff and solid pizza. Thin crust. I asked my mine well done and it was perfect. HIGHly recommend 👍🏼

It was okay. Came on the weekend got a couple slices. Tomato tasted old. Staff was nice but music was super loud couldn’t hear a damn thing. Probably wouldn’t order here again based on pricing and overall flavor.

The pizza is pricey, but it's really good. We come here often. Staff is friendly. If there is something wrong with pizza they are always agreeable to make things right.

Pizzas are huge. Food was pretty good. Service was excellent. I would recommend this place for a good slice.

The Maverick was a unique and yummy pizza. When I'm back in town, that will be my go to. Delicious local pizza. Eat local!

I come here almost every weekend as my reward for the week. Never have I had a bad slice, not to mention the huge size for what you pay! Great service as everyone is always friendly and very quick to take your order as soon as you walk in the door.

Big slices pizza. Always thin crust. Simple, rapid fast food and delicious Not for a romantic date, not a fancy restaurant Is a grab, eat and leave !!!! Which is exactly what I want when I go to visit it

The food was tasty and the service was awesome! The lemonade was great, and the huevos rancheros was pretty good as well, but not particularly memorable. Overall I enjoyed it and would go again.

Big slice NY style pizza. Order by the slice with toppings or get a whole pie. I add extra cheese, because the 'red' slice doesn't seem to have enough. Good for a drop-in lunch.

Amazing pizza by the slice or you can order a whole pie, but that's a ton of pizza! The old school pizzeria feel gives this place a very welcoming personal feeling your won't find with the mainstream pizza joints.

Had take out. Did not feel that the pizza was worth the price. Average at best. Also, even after the transaction was completed online, they still ask you to sign a paper copy at the store. This is just for adding the tips. While I understand why they do it, it is much better off including it in the online portal itself so that it is all one transaction.

4$ for a huge slice of 🍕 50 cents per additional toppings. Good deal. Hot, fresh and tasty 😋
