I've ordered over a few dozen times. I've gotten it delivered hot once. Pizza is decent for Colorado, but the slowest delivery in Boulder. read more

Cosmo's Pizza - Seems like it was in the refrigerator before we got it. - Pizza Near Me - Boulder, Colorado

Pizza is fantastic. Its greasy and the slices are huge. You don't come here for gourmet pizza, you come here for good pizza. Oh and the spicy ranch is the perfect compliment. read more

When we walked in, we were hit by the amazing smells of cooking pizza. We ordered a medium supreme, veggie calzone with chicken and a salad. The portions are on the large size so this was more than enough for our group of four people. Called in the order for pickup and everything was ready when they said it would be. Delicious! read more

Cosmo's had been my favorite go-to place in Boulder for a good, inexpensive slice - until this evening. Super-disappointed in the snarky attitude of the person taking orders, to the extent I will find alternatives in the future - even if this means paying more $ the next time around - rather than frequent Cosmo's again. read more

Top-notch pizza. I would recommend it 10 out of 10 times. I have a slogan for their T-shirts "great pizza bad attitudes" I must assume the person taking orders goes to CU Boulder and is going to be the 21st astronaut in space from that school the way they talk down to customers. I look forward to having my next slice delivered. read more

The pizza is pretty good, they have the great spicy ranch, and the same menu as the hill location. IT isnt as good, maybe the pizza maker was off, but it never seems to be as thin and crispy as the stuff at the hill location. I go here when we dont feel like a venture to the hill and looking for a parking spot etc.... read more

Best pizza place in Boulder. Amazing taste, friendly staff, & Never lie to customer (some store like "boss lady xxxxx"). If you are looking for something legit instead of paying review crabs, try here! read more

Cosmos pizza is an interesting place to grab a slice. Compared to other pizza joints around boulder it is most definitely a step above the other chains in the area, what bothers me about cosmos is how they treat their customers. There are two cosmos in boulder and i would not be giving a 4 star review if the cosmos on the hill hadn't made upfor the horrendous service at the cosmos on baseline. The one on baseline has a cocky vibe like they think there pizza is so good they don't have to be kind and courteous to there customers. If this place was any other place than boulder I don't think it would last, ive never had a problem at the other one, but hey the pizza is great and everyone who delivers is mellow and cool so I stick to the delivery option. I would recommend getting the extra large, the pizza is massive and perfect for party's or a long night of bong rips and beers. read more

Cosmos fed the film crew of Pioneers in Skirts www.pioneersinskirts.com We had a pepperoni and sauasage, and a feta, spinach and artichoke pizza... AMAZING! Thank you so much... XO @WomenPioneers on Twitter read more

The pizza is fine when it's fresh. It's not my favorite cold pizza the next day. They sell a garlic ranch sauce that makes the pizza taste good.. it's basically code that you buy the sauce at 50cent per cup. That's all well and good but the legit pizza places back home don't need to dose the pizza with a ranch sauce to make it taste good. I imagine anything would taste good with a garlic ranch sauce. Still better than Abo's. read more

Really good pizza. It's best to go in and get a slice (they are huge). And definitely get it with spicy ranch. Mostly a college spot and filled with drunks at night. It's usually pretty good delivered too but can sometimes be hit or miss (I've ordered at least 50 times - yikes - and it's almost always good). They also have good breadsticks and if you get a large drink, it comes in a cool reusable cup with lid. read more

Really large slices (New York pizzas got nothing on these bad boys) and phenomenal customer service. Would recommend to anyone looking for a late night bite. Just be warned that one slice may be enough. read more

I was born and raised on the south side of Chicago so I'm quite spoiled when it comes to pizza. Been on a road trip for the last few summers and Boulder is always one of my stops and I ALWAYS get Cosmo's Pizza because it's stupid good. It certainly isn't Chicago pizza but one of the best places otherwise. read more

Amazing pizza, must get the spicy ranch with it. very friendly staff however when they get busy they have a tendency to forget slices or it can take a while. But would definitely recommend Cosmos and they are also open late! read more

My friend and I visited the restaurant on this Friday. A women with short hair and wearing a bandana who said our food was ready was extremely rude and unprofessional. The restaurant was decently loud, making it immensely hard to hear. She told us we "needed to listen better next time" and that "she had a loud voice and we should of heard her". It was an extremely displeasing and horrible experience and it made me not want to visit that cosmos again even though the food is good. read more

I work for a company that gets pizza delivered once a week and we always choose cosmo's. Not only do they have the best customer service, Ben called one day that I forgot to put in the order and completely saved me, but they also have a huge variety. I would absolutely recommend this to anyone ordering for a large group of people or that just wants a quick slice. read more

This location is a complete disappointment every time. Every time I've ordered a pizza from this location, it arrives cold and barely any cheese on it. Last night I asked them over the phone not to knock since it was late and not only did they knock, they were loud at the door when I answered. If you want the best pizza in town, go to Abos. Those guys know what they are doing. read more

I ordered a catered lunch from ezcater.com but accidentally left it in "draft" mode. . Didn't realize it until I was looking for my "it's on it's way confirmation" . . Dying!! I decided to order pizza, but only had one hour to get it here. So, first spoke with someone at (not sure what store) that pretty much HAD to be stoned out of his gorge and completely wasted (15min) my time - Just zero reality connection there (I'm pretty sure I drive behind him occasionally on the freeway!). Upon ending the frustration, I called the Baseline & 30th store and spoke to Tercia, the Manager, whom not only took a massive RUSH order but was AMAZING!! I ordered 6-7 XXL pizzas, 4 salads, breadsticks and more. . It literally got here in 35 min. I honestly can't even find an adjective that describes how grateful I am. Not only that . . but the pizza ROCKS! Thank you EVERYONE at the *Baseline Store for knocking that out in record time!! Next time I will order in advance, but I will definitely order again!! Many many thanks!! read more

Their calzones and spicy ranch are very tasty, especially on a cold snow day. Their pizzas are super crispy and yummy. Usually crowded with college kids. read more

Great large slices of pizza. Amazing sauce and ingredients. Delivery was quick and no problems.

Yum. Lucky Boulder folks. My trip here was not for pleasure. I was weary and out-of-sorts, and then someone suggested Cosmos. Brought a take out order back to the hotel room. It hit the spot. Love the thin crust and everything else. Highly recommended! read more

We used to order from Cosmos al the time but 3 out of our last 5 pizzas have had the wrong ingredients. The straw that broke the camel's back, and why I won't order from Cosmos again, is their ridiculous boost in prices, that they blame on the sugar tax, making what used to be a semi expensive expensive pizza now into the most expensive in town. Not good enough to spend almost $20 before delivery tip on a pepperoni pizza. read more

BEST PIZZA EVER!!! As a college student, I appreciate their cheap prices and late hours. The spicy ranch is a definite must have. Also, their pizza slices are huge so plan according. read more

Great Atmosphere and Great Music. Love the food, and love how cheap the food is. My personal favorite is probably the meat Lovers pizza, although it changes daily. read more

Today was my first experience ordering from Cosmos, and let me just say first -- delicious pizza and spicy ranch. However, it was the customer service that was excellent. I initially ordered take-out, but soon discovered I wouldn't be able to drive there since my car had been booted. I called to tell them this and switch my order to delivery, and they brought me an extra pizza because the first had gotten cold. Delivery was fast too. Thanks guys!!! read more

This a great pizza place. Slices are huge, almost 3x the size of a normal pizza slice and hot when you order them. The staff are so friendly and the environment is laid back and welcoming. Definitely would come back again and again. Their lunch specials are cheap and offer a good deal. 10/10 read more

Good pizza. I like eating it drunk. I like eating it regular too, but drunk makes it better. If you don't get the spicy ranch, what the shit is wrong with you? read more

Great place to get a massive slice of pizza on lunch for a fair price! They have a cool set up where you can take your pick from their rack of pizzas, and they throw your slice into the oven and you get a freshly cooked slice of pizza about 3 minutes later. read more

Delicious breadsticks and pizza. Pizza was kind of greasy but the taste was really good. The size of the slice was perfect for me.

I ordered a salad (garden) and pizza (veggie supreme) while staying at a nearby hotel that doesn't have a kitchen in-house. Delivery took almost exactly TWO HOURS, and they didn't even include a fork with the salad. The food was also mediocre, so overall this was a very disappointing experience. read more

I ordered delivery from this location and the driver refused to bring the pizza to my apartment door and told me I had to come down and get it. He was rude and cited this was due to it being a "private building". I refused delivery and called back the location and spoke to the shift manager who mentioned what the driver said. When I asked why they are the only delivery service in Boulder that doesn't enter apartments (they've delivered to my door before lol) the shift manager said that they encourage their delivery drivers to stay on schedule and not fall behind. The funny thing is that I would've taken more time getting dressed and going downstairs than it would've for him to come to my door. I'll never order delivery from here again and apparently they'll never again deliver to my building - obviously not my actual door since they won't come in the building. read more

Extremely poor customer service and driver gps service/directions are not correct. After a handful of incorrect orders and cold pizza due to lost drivers, we're calling it quits on Cosmos. The managers really should learn how to be better business people. read more

Worst service ever. Chick with tattoo on left shoulder handling the cash register obviously doesn't know how to treat customers. Literally just made a yelp account to make this review. Shocked. read more

Don't get delivery here. Driver literally dropped the pizza and said " not my fault " driver looked high. Good one delivery boy

Absolutely awful pizza, came undercooked and of poor quality. The salad was ok besides the mealy tomatoes. Not recommended.

I had this restaurant described to me as 'y'know, college pizza' so I really wasn't expecting much. It was 2 pm, I hadn't eaten at all yet, but didn't want to eat a lot, so I thought I'd order 'just a slice' of their meat lover's. I thought it was a bit pricy for a slice and a soda, but then my order came up. The paper plate was not big enough for what was on it! Definitely required two hands, or folding in half. I would have considered it two slices of an extra large pizza, so I think I got my money's worth. The crust was crisp without being hard, which is hard to accomplish. The place was clean and bright, and the workers were singing along with the music that was playing, so overall it was a very nice atmosphere. They have a counter height community table and another soloing it counter, all of which were ridiculously high. It's been a very long time since I've sat at a table that came up above my chest! read more

I went to Cosmos for the first time a few weeks ago and I am not from Boulder so I have never tried it. I am gluten intolerant so just to ask out of curiosity (figuring they might have that option since it is Boulder) I asked if they did have a gluten free pizza. One of the guys that I asked proceeded to make fun of my question and mock me by saying "We don't, but I can give you water and tin foil that we use to wrap up to go orders". This really struck me and made me feel hurt. He proceeded to make side comments about it and I just had to walk away. I was simply just asking if they had gluten free, I did not expect them to,but he was genuinely rude and acting like he just assumed I was gluten free for the sake of it being a "trend",when I really have an allergy. I will never go in there again unless the employees are taught common courtesy and manners to all customers. I feel like this really needs to be addressed and I hope the manager sees this review. You can simply say "no" and not have to make a person feel bad. read more

If they had a minus one star this would be the assholes to give it to, although the pizza is good, the ranch dressing is bomb, the staff here are such rude bastards it's not worth the hassle!! The girls are all nice but the guys who work here are rude rude, they treat you like they are doing you a favor for you bringing your business to them, the manager is super dick!! Don't bother w a compliant cause he dont give a shit, and will tell you so! And the drivers omg, what douches, everyone of them has the loudest bass and rice burners where the eff are we Los Angeles no.... and if you are trying to be an incognito stoner, why do you need the loudest stupidest car to draw every eye to your car, what did you not get enough attention from your parents, now you have to solicit attention at all times, from the entire world?? Grow up, grow a pair, and stop peacocking around, super unattractive, fucking 5 year olds w a license... scary. You morons give a bad name to stoners, move back to wherever you came from, please!!!! read more

The oven was broken. The bottom was vastly overcooked and the outter crust was white, not golden brown. I was offered a $5 credit (on a pizza that cost $16. I gave 2 stars because order taker was OK. Won't Be back, Save your money. read more

Great pizza all fresh ingredients! I'm from chicago and know good pizza! It's all handmade with love. Glad the they are here! Great service too! read more
