Pretty good NYC style pizza. My only beef is that I ordered jalapeños, & they think that the ride through the oven is enough time to cook the raw jalapeño... It is not! I've since switched to Denver Pizza co. read more

Great pizza! Fast and friendly delivery. Will definitely order again!!

Got off work and my boyfriend and I couldn't decide on what we wanted. Cosmos was the first up in GPS at that time of location, so we gave them a try. Good pizza, it's just I love thick crispy crust and their crust was just to thin for me & I didn't see any other options. The spicy ranch was definitely on point though. Super cool nice dudes in there as well! read more

We've had Cosmos a handful of times over the last couple of years. Usually the pizza is really tasty, if you're willing to pick it up. We have found that their delivery area stops about 1 mile away from their front door as their drivers must be walking to get it where it needs to go. Everytime we've called to grab a pie, whether it be a Monday or a Friday they see 'too busy' to drive 2.2 miles away. Good luck to them, and to you if you're not willing to go to them to get your pizza. We've moved on to Sexy Pizza. read more

I came in to check out the pizza and was pleasantly surprised. The staff were friendly and made sure that all guests were served quickly. I ordered a couple slices and had some extra toppings added. They crisped up the slices in the oven for me and they were delicious. The slice size is generous and pizza quality provides very good value. I'd definitely go back. read more

Cosmos pizza is delicious, and the spicy ranch is the best I've ever had. They also sell the spicy ranch by the jar as well. The staff has always been very kind and fast. If you have a hankering for some solid pizza, cosmos is the place to go! read more

This place BLEW my mind the first time I tired them at the beginning of the year (Jan. 2013) and continued to do so for the following months! I remember this one time I placed a REALLY late night order (after a long day of work) and it took a bit longer than usual & the manager called me to let me know he was on his way & when dropped off the pizza apologized again for vein late, he explained how he was the only one left at the restaurant & had to lock up before he could deliver something like 10pizzas! And the pizza was still fresh an amazing! I used to brag about How I didnt know a pizza could come that fresh! The mind blowing freshness of the l finished product was just, fresh hot steamy & cheesy good! HOWEVER, THERE ARE BUMMERS: what happened to you guys? I feel like some one was just being lazy. The pizza tasted like it was OLD or re-served me an already PREMADE pepperoni pizza that they just thew additional toppings on & stuck back into the over to reheat it. Gross. It was by far the most disappointing, disgusting pizza I've ever had. It was soaked through the bottom of the box and the whole pizza was wet & soggy like it sat in water and was just inedible. I was so sad when I called to explain about my icky pizza and the person on the phone acted like they didn't care and the I was lying. Then when I tried to tell him how I've loved them in the past he got very impatient and somewhat combative & never apologized... They sent out another pizza to replace the first that wasn't soggy but it was of the same, stale re-used quality. I haven't ordered from them since. So sad. Pull it together Cosmos, I want to love you again so bad! read more

Disappointed in the pizza. Cosmo's is nearby and I was hoping for better. The pepperoni was okay but the Greek Veggie was so bad we threw out the leftover slices which I never do. There is better pizza to be had nearby. Won't be getting pizza there again. read more

Love their calzones and pizzas! The spicy ranch sauce is awesome! Fresh baked and hand made fresh

I love this place. The guys are nice. if you dont like the soft crust ask for a lil crispy. Their ranch is good as well.

The place was pretty good besides the breadsticks simple just dough with no seasoning or taste. Overall a good experience.

Decent 'za, but not the most consistent. Love the spicy ranch for the crust, though.

Delicious pizza, great service and friendly staff! What more could you possibly ask for?

Cosmos is one of my go-tos. Its delicious and I'm never disappointed. Everything tastes amazing and they have a bunch of different toppings so you have a lot of options which is wonderful. The employees are always friendly as well. Yuuuuummmmmmm. read more

We ordered pizza at 3 am and it came hot, quick and oh god so good. I honestly didn't expect much for a late night pizza delivery and they nailed it! Yum yum read more

I have the same pizza delivered every time, Hawaiian add jalapeños. I order a lot, probably at least twice a month. And it's always so damn delicious. They are friendly and fast, and tonight the delivery guy was especially rad. (Glasses and go-go gadget pen. I'm talking about you) I love cosmos, and you will too. read more

This pizza is delicious. Top three favorite in Denver. I get delivery from them. I've ordered twice so far, the food arrived exactly as I ordered it, faster than I expected it to arrive, the delivery driver was courteous each time, and I really enjoyed the spicy ranch sauce with it. This will be the only pizza I ever order for delivery EVER again. read more

To the guy answering the phone at 2am on 2/18/17- if you don't understand customer service, you probably shouldn't have a job that relates with customer service. I work at a hotel in downtown Denver, and yes some days can be hard, but no matter what I know that you always wear a smile and treat customers with respect... Cosmos, we tried to give you our order (Medium pizza with half sausage half pineapple with extra cheese). The guy taking orders over the phone said "got it" and hung up half way through our conversation and before we could even say the ending to our order. We called back immediately and asked why he decided to hang up WHILE we were ordering and asked if he could confirm our order. (Same guy we just ordered from before getting hung up on) He actually sounded a little shocked that we called back and said "half pepperoni and and half pineapple." You could hear in his voice that he could care less. We told him that his behavior was rude and that it was the wrong order since he hung up on us half way through our conversation and how could he know what our order could have been anyway? After all of this HE TOLD US ON THE PHONE THAT WE WERE RUDE, laughed and hung up AGAIN. Really disappointed with Cosmos tonight and we didn't end up getting our pizza since we didn't need to deal with that. Maybe this guy should be fired or should not be the one answering food orders, just sayin'. Or maybe he's better at tossing pizzas without any communication towards others... I'm not even the type to write reviews, but this was ridiculous. We know you're busy, but customer service comes first (let alone allowing us to have our whole order heard before you hang up twice and act like a 12 year old). read more

Delicious Pizza! Also must say, the service has improved significantly! After this Cosmos opened in Denver I felt like the pizza and spicy ranch was on point, but some of the staff didn't have much customer service experience/didn't have much training on it, but that has changed! This is one of my favorite pizza places in Denver! read more

Best pizza in Denver based on plain slices. I have tried most places around and this is the best. Plus the staff is always on point and super friendly. Go, go now. read more

I order a larger sausage and pepper pizza 01/31/04 And the Sausage could taste it and pepper where hard and The Pizza was Ice cold! The crust was very hard. And the price was to high for one pizza! read more

It's 1:25am and I just finished eating half a calzone that I spent 10 bucks on. So not only did I satisfy my late night $10 snack budget and craving I've got lunch tomorrow now, can't beat that. Most importantly it was delicious. The staff was friendly and I enjoyed the music they had in there, but I can see where they mostly appeal to a younger crowd although at 21 I'm cool with that. Cosmos is for sure worth checking out read more

We used Cosmo's to deliver our holiday office party....the entire experience was sheer perfection! The young men that helped me really listened and took great notes. They were so patient with me as I explained a very complicated order. I went down the night before and gave them a list of who wants what salads, different dressing, very complicated order for over 20 people. I asked for special pizza's too. We had a limited amount of time so the order had to be there at 12 noon. The food arrived right before noon, perfect timing, the pizza was delicious and really hot - and the complicated salad orders were completed perfectly. Cosmo's at no extra cost supplied all of the cups, plates and napkins. That's to them, for a brief shining moment, I was the office hero. Another team liked our service and food so well they too, ordered their team's Xmas party from Cosmo's too. Thank you dear Cosmo staff, you are the BEST cooks and you meet and exceed my very best expectations!! read more

Fast delivery time, delcious pizza crust and sauce and really reasonably priced! We always order the pepperoni pizza and jalapenos. Its cooked to perfection and the amount of toppings is perfectly in proportion to the sauce/size of the pizza. We order from them once a week and it never fails to be the best. read more

Best Pizza Ever! I always wondered what it would take for me to give the coveted "5 Star Yelp Review" to a restaurant I always imagined it'd be like a diner or perhaps a steakhouse of some sort, but never in my wildest dreams while I entered Cosmo's would I think that this is what 5 Stars looked like. Inside is so tiny you could probably only seat 10 which is okay cause they have carry out/delivery for you at-home eaters. Their menu was small and easy to read you can order pizza by the pie or by the slice don't worry they also had the usual pizza place extras like Calzones, breadsticks salads etc. When you've decided what you want the pizza is displayed precooked, you can add toppings(which they have several) or keep it as. Either way you decide it's going to be made to PERFECTION. I don't know if it's the sauce, the cheese the thin crust or some secret mojo but somehow all of it formulates to the ultimate pizza! Oh and another thing like if you needed even more convincing, the slices are huge and the prices are small! read more

See all

This is my absolute FAVORITE pizza ever!! And their chipotle ranch...to die for!!! Highly recommend!!! read more

These guys have huge portions on pizza, calzones and salads. I think their pizza can be a little oily. Especially the meat ones. So I'm not really a fan of the pizza. I'm a fan of their salads though. For like $9 it's enough for 2 meals for me. 2 window slice and a drink lunch deal is like $8 and that's also 2 meals worth so I split it with someone. I forgot how much the calzones are but it's similar pricing and portions. I don't think the flavor is anything to rave about. Definitely get the spicy ranch though. That is good ranch. read more

They've just raised their prices substantially, but did NOT change the prices on their web site or online menu. They tried to charge me about $8 more than the price on their menu, and when I asked the guy on the phone to go over the charges, he was rude about it, suggesting that I didn't understand sales tax or math. I finally got him to acknowledge that the computer he was taking orders on was ringing up prices higher than those published on the web site, but he said there was nothing he could do about it. Double-check and triple-check their math. Until they advertise the same prices on their web site that they'll charge you over the phone, you're in danger of an unpleasant surprise read more

This place sucks! I found a staple in my pizza. I expected them to apologize and give me some sort of compensation. All the guy said was "it's an extra topping!" After a good five minutes of them pretending nothing had happened I asked if they were going to do anything about the fact that there was a piece of metal in my food. The guy sarcastically said "what do you want two free large pizzas" and rolled his eyes and walked away. I finally ended up with them giving me two free slices of pizza... Woohoo! I wouldn't waste your money here. There are better places that have a better staff and better food. read more

Gregory goes above and beyond. I asked Gregory for a special request on my lady's special day and he delivered with flying colors. Gregory for president!! read more

These idiots are so rude it's sickening. Orders that never show up, A-hole employees, disgusting ingredients, notorious for calling it quits about an hour before their closing times... what a joke. F- Cosmos pizza. Don't eat here - plenty of other places to get late night food in this city! read more

I only give one star because of the kindness offered by a manager at another location. I am housesitting for the holidays a few blocks from where I used to live. I am ashamed that I ever made a purchase from this establishment. My experience has been abysmal AT BEST. The truth goes like this: I call in, and order a pizza. Normal right? Then, I informed them, yet again, that I have a dog that barks. Please, call me as to deter The precious pup from barking at delivery driver. Then, driver shows up. No knocking, just continuously rings doorbell. No respect for comments on notes. then, he has already opened storm door. No wonder we have a storm doors? Total disrespect. Then, he shoves pizza into my breast area. I hand him a 20 for my $16 pizza. After he made a very nasty comment he threw my change into the snow. Saying he didn't want my money anyway. I attempted to call the restaurant multiple times. They continuously hung up on me over and over and over again. Manager continued to tell me that his name was Ralph. I asked him if he could even remember the last name of Ralph from a Christmas story because he was continuously disrespecting me. I, had the presence of mind to reach out to another location of cosmos pizza. I spoke with a woman named Tertia that was kind, empathetic, and did not appreciate the nastiness that ensued by the Denver location. She however, ensured me that the owner would be notified of their faults. Until this situation has been resolved, I will no longer, EVER, eat at Cosmo's again. I also, will discourage others from ever patronizing this pathetic excuse of an establishment. read more

Super friendly on the phone, the order came crazy fast and the pizza was bonkers good!! I'm from New York and Cosmos is the best I can get here! read more

The Pizza is okay. No one wheres gloves, unless instructed to(rarely), honestly. I sat there for a while and noticed how they treat the VERY FEW women that work there. It was sexist to say the least. The men are of course having fun, disregarding customers, and making fun/ treating the female employees like shit even though it seems like they were doing the most work. Unless you hire more colored people or women, I won't be coming back. Shame on you (most likely a man.) who hired these shit heads to run your restaurant. Adam and other owners, get your shit together. Also clean your bathrooms at night. They are ok during the day, however no one gives a second thought after 6pm and it's disgusting. read more

We've been going to this pizza joint for about a year now, but that all changed today when we ate at the bar near the prep area and saw a worker blow his nose, turn around and start kneading dough without washing his hands. Common sense, man! Nasty. read more

Maybe it's because I had leftover pizza, or maybe it's because I didn't get to try their special ranch, but I honestly thought this pizza was just ok. It was a little reminiscent of cardboard, but the toppings were good. read more

it's awesome that they deliver so late but the pizza is just okay. the breadsticks I got were doughy and felt undercooked and lacked any seasoning at all. the spicy ranch is delicious but it doesn't save the place. also, the delivery guy made me go outside to the corner to get my pizza. I understand they are busy but it was thoroughly awkward. read more

Maybe it was because we went at 2 in the morning, but I was not impressed. The pizza was hot (too hot), but it didn't have much flavor. The staff was incredibly nice and gave us all of their leftover slices for free. However, none of them really tasted good. I would not return. read more

Adequate pizza with no extra charge for delivery.

Okay. Beats dominoes. Ordered a pizza for takeout and felt kind of ripped off after seeing the huge pizzas they sell by the slice. Probably cheaper just to grab a few slices to go than order a pizza for takeout. read more
