Probably some of the best pizza in Boulder! As a New Yorker I love New York pizza - Cosmos comes as close as it gets! The staff is friendly and extremely accommodating... I personally love my pizza right out of the oven fresh... They're always willing to accommodate. Oh, by the way... They serve it by the slice and that's how I love it right out of the oven. read more

The workers are very nice and it is always very clean but when you walk in the door it smells too much like Lysol lemon scented cleaning spray. cosmos on baseline is so much better because it's so stinky when you walk in so maybe if they made this one stinkier I'd like it more read more

THIS is pie/pizza by the slice. You know that scene in the Goofy Movie with the pizza slice? Yeah thats Cosmo's. This is the kind of pizza I envision when it's friday night and I need something to pair with my Coors Banquets. Real pizza for real people. read more

Cosmo's Pizza - Pizza Near Me - Boulder, Colorado

this pizza is just so surprisingly bad. I have tried it multiple times now and over and over again I get a slice of pizza with tomato sauce that has some flavor and absolutely flavorless cheese and crust. It's like they used cartoon cheese instead of real cheese. This pizza is terrible. And I have tried many times... never again. read more

Great pizza when you ask them to toast it extra!!! Large slices for sure and quick service

Hella chill staff bomb food 10/10 no notes jalepeno popper pizza so mmmmmmmmmmmmmmmmmmmm

Staff was quick and friendly. Food is decent I am not from the Boulder area so maybe it's good compared to what's available. Sauce was too light, good cheese, sausage was odd and pepperoni was good. Dough could be crispier read more

THIS WAS AMAZING. We come from texas so after a 16hr drive this definitely made everything worth it. read more

Cosmo's Pizza - Pizza Near Me - Boulder, Colorado

Well back in college I visited a friend in Fort Collins once for a long weekend. Yes, you know what i'm going to say. We ate some pizza from this cosmo and I guess the spicy ranch stuck with me. Thousands of years later my partner and I are checking out Boulder and we needed a lunchdinner. We were famished and happy. After accidentally ending up in the college restaurant area of this town surrounded by scary loud boys i ditched all my hopes and dreams of getting some sort of veggie tales dish and said let's just get a pizza and get out of this loud boy area. That's exactly what we did. At first I couldn't remember what this place is called ... Carlos pizza... Colins pizza... capricorn pizza I don't know... spicy ranch ...COSMOS PIZZA ! That's what it is. Well five stars because it's pretty good and I added a bunch of stuff and swapped and the whole nine yards on my pozza and they got it all right. Also. They are not wimps on the sauce. You get a real serving of the ranch. Thank you cosmo and thank you to the cosmos for this linner. It was great to get away from those terrifying young men and end up in the cosmos with some spicy ranch after all this time. God bless read more

Entire pie was burnt on the bottom. Ovens should be cleaned daily this is completely unacceptable. I threw the whole pie away because my dogs wouldn't even eat it! Wasted $30 and my kids are still starving. read more

Great 24" pizzas. Delivery ran a bit late, but pizza was hot. Love the white pizza the most. Never disappointed in Cosmos.

Decent pizza, and I'm a NY pizza snob. I love the chewy crust, and the plentiful topping choices, and the spicy ranch sauce is great, though personally I don't dip. Pricing is also reasonable. I've been ordeing delivery lately, as Cosmos is one of the very few places that does its own delivery instead of using a third-party service. The pizza always arrives on time, hot, and delish! read more

I LOVE this place. They are always friendly and ready to help. I have been going here for years, and even during COVID, I was always treated great. There was one young man, Travis, who would bring the pizza to my car hot, complete, and accurately when I phoned in an order. Now, I have had great interactions with a new girl, I think her name is Astrid, who is very personable, friendly, and good at her job. I love the pizza, the MAVERICK is my absolute favorite, With spicy ranch read more

This restaurant DOES NOT serve gluten-free pizza, contrary to what they claim on their menu. They serve "gluten lite" pizza, aka pizza that will make you very sick if you have Celiac disease or gluten intolerance. I reallllllly wish restaurants would stop lying about allergens in their food. This is the equivalent of a bakery saying they have "peanut-free" cookies and then rolling all the peanut-free cookies in peanut flour before serving them to unsuspecting allergic customers. Fortunately, or unfortunately?, gluten doesn't instantly kill you if you eat some. It kills you very slowly, over decades, through malnutrition, chronic diarrhea, osteoporosis, arthritis, non-Hodgkins lymphoma, and all the other fun stuff that's caused by gluten when you have Celiac disease. You also get other non-fatal fun stuff with Celiac disease, like itchy weeping sores on your skin and your hair falling out. STOP CLAIMING YOU HAVE ALLERGEN-FREE FOOD WHEN YOU DON'T! YOU ARE HARMING PEOPLE. Two stars because BF and I thought the pizza was tasty, even though it made me sick later. read more

Came here after climbing at the nearby Movement Gym - one Mediterranean pizza slice w/ the SPICY RANCH (of course) really hit the spot. Don't even bother thinking you will be able to share one spicy ranch - just get one per person. Definitely would return again after a hike in the Flat Irons or another climbing session at the gym. read more

Cosmo's Pizza - Mediterranean veggie pizza slice. - Pizza Near Me - Boulder, Colorado

bit into my pizza, and found burnt charcoal pieces of other crust stuck to the bottom of my slice. i called and all they said was "oh yeah that happens." no apology, just a refund of this one slice. and this was after i already didn't get the spicy ranch i'd asked for in my original order, and they were not helpful on the phone then! no dinner for me tonight, won't be eating this for sure. the way i was talked to on the phone the second time was bad enough to come here and write this review. i bit into something that, frankly, doesn't look all that sanitary and their attitude was as if this was just a normal occurrence. i have been eating cosmos for years but this here is straight up not good pizza. why i'm really here tho is because their reaction to it was even more upsetting. they did not care that they are serving food like this!!! tldr check your crust, because this just "happens sometimes" at cosmos, leaving you shit out of luck with no appetite read more

I went last night for a pizza and they started rushing me while I was eating definitely would not recommend it. Service was horrible asthrid the cashier girl was sweeping while we were eating she couldn't even wait for us to finish just straight rushing us . They did not have napkins , tables were dirty , there ranch tasted expired and they charged us for plates Overall 1.5 outta 10 . Would not recommend this place . read more

Best joint in town. Used to come here all the time with my friends and the pineapple pizza is to die for.

My husband was very excited to take me here because this is all he ate in college. I was very disappointed only because the pizza was just ...pizza. It wasn't good but it wasn't bad. They have a signature spicy ranch sauce. I wasn't impressed either but it does have a kick to it. read more

I have eaten pizza here dozens of times over the years. It is consistently good with plenty of cheese and toppings. Not pizza from the lower east side but slices as good as you will ever find in Colorado! read more

My friend and I ordered a 24" 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 get our refund, we noticed the man making the pizzas had a beard and wasn't wearing a hairnet on his beard. I will never go back, and suggest that you avoid this place if you like your food hair-free. read more

P is for the way they present such beautiful slices of cheese and goodness. I is for the way they always inquire about if I am having a good day. Z is for the way they always seem zealous about their craft. Z again because even Zebras would eat here. In fact, they might currently. Stay woke. A is for how awesome this place is all around. Legendary pizza, good vibes staff, and always good prices to keep the working man happy and fed. If pizza is love, these guys are Bob Ross. read more

I was not given a box and my piece was ruined from it being placed into only foil ripping the cheese off when I removed the cheese

I've been coming here for a very long time, and I'm finally sick and tired of being treated like it's an honor and pleasure to be served by you. Your pizza is mediocre at best, and your staff on average has piss poor attitudes. Why have I been patronizing you for so long? Because you were the only option most of the time. Your are offensive in every way. It boggles my mind how you are still in business. For those of you reading, do yourself a favor, skip this place and go to one of the many great pizza shops we have here in boulder. Brooklyn Pizza, Pizza Calore, Back Country Pizza...just to name a few. The level of stars that has the most votes for Cosmos is '1'. That should tell you something. read more

I am from Boulder, yes actually born here. I have tried every pizza place in town, and cosmos is better than most. I have rarely had delivery, and the negative reviews seem to mostly be issues with delivery or people butt hurt about the covid restrictions. Audrey Janes has fancier toppings, and this is the one area that cosmos could improve. I would love to see roasted red peppers, grilled onioins, burrata mozzerella or some more interesting veggies added to the menu options. However cosmos crust is so much better ! And you can buy a pizza for a reasonable price where as Audrey's is considerably more expensive. The guys are always friendly here, and the few times they messed up an order the immediately offered to remake it or comp us for a future pie. Every time I have a friend in town I always order a pizza from Cosmos and Every single person has said it was one of the best pizzas they have ever had, including my east coast friends. read more

I go here often and love this pizza. The slices are huge! Be sure to get some spicy ranch to go along with it.

I always order from Cosmos because they offer vegan cheese. Over the years I've ordered from them and the pie is always delicious. :)))))~

I love Cosmo's pizza at Baseline. It is like the NY pizza. But the same pizza here on the 28th Street is like the one from Pizza Hut. Very different. It was not like that in 3/2020 when The pizza was just like the one in the Baseline store. Wonder what happened. We order from the Baseline store now. read more

It's a good slice that's consistently prepared. It's NY style and always fresh and delicious. If your a pizza fan I give it a OneBite score of 7.7 it's a very good slice and is also great at all locations I have had it. Staff is always on point also! read more

THIS PLACE IS BAD. They are rude and the service is terrible. Pretty unhappy and will never return.

Either incompetent and/or lazy service (May 26) The problem is that I wanted to order a mushroom pizza. The guy helping (not very helpful) informed me that he cannot take the order at the door. I have to call the order in... even though I'm standing (masked and gloved) at the door. This seemed incredibly stupid, so I double checked that he cannot just take my order and that I need to call it in... Yes. That's correct. **With so many businesses struggling and even more that will struggle, please do not support businesses that don't care** Please consider instead: Boss Lady Pizza Nick-N-Willy's Pizzeria Locale Pizza Colore Brooklyn Abo's Proto's Audrey Jane's Backcountry Oregano Cheers! read more

This is quite literally the worst pizza I've ever had in my life. And I'm even high. I'm supposed to write more words but there is nothing left to say. read more

Caution: no idea how they calculate current wait times (before you place an order). Initially a 25 minute wait for pick-up (of 1 Calzone) then became 1+ hours after placing the order. Then once I arrived there at the 1+ hour mark was greeted with "wait in your car until we call you" sign (without ever mentioning they'd call me during the initial purchase before wasting my time sitting in the parking lot). Don't worry, I'll never make the mistake of ordering from here again. -- Update: The lady who canceled my order, once it got to 2 hours without receiving a call after going home, was very nice & polite though. read more

If you like a pizza with toppings all the way to the crust, this is not the pizza place for you. I liked the taste of their pizza but after four times of their sending me delivery pizza with the toppings all in the middle, 3.5" from the edge, I switched to Pizza Colore, also in Boulder, similar pricing, better sauce, and toppings all over the pizza. The Cosmos staff will also tell you that YOU are the problem if you call to complain about the toppings being in the middle. Don't buy from these people. read more

Boulder has so many good pizza places, why would you go to Cosmos? Give Brooklyn pizza a try. Life is too short to stuff mediocre tasteless pizza in your body and feel it sit there for a few hours while your body tries to figure out what to do with it. I think Cosmos is cheap, and that might be all it has going for it. For slices check out Brooklyn. For crummy to go pizza I think Blackjack is better. For whole pies get Brooklyn, backcountry, or boss lady. For neopolitan check out Protos. Cosmos isn't all bad, but it's just mediocre. read more

So I've been coming to the north boulder location since I moved, and every single time I order, something has gone wrong, and it's getting to the point where tonight will be the last time I order anything from this location, and I will happily drive to the location at Baseline and 30th that actually has its shit together. Tonight they forgot my spicy ranch, previously it's been that I've gotten a pizza delivered 1 hour past the quoted time that wasn't even cut. And that isn't all, but It's a bunch of bullshit. Management needs to step it up at this store because, fuck. You're clearly not paying your employees enoughh to give a damn. read more
