    Pizza

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

    Coming from Houston with my family and we all enjoyed this huge pizza we were all stuffed and the spicy ranch was amazing, will definitely come back again one of the best pizzas I've ever tasted!!

    Greek veggie but I added a bunch of stuff and changed everything

    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

    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.

    Mediterranean veggie pizza slice.

    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.

    cheese pizza with some "oh yeah that happens" bits, apparently

    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

    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.

    Hairy pizza

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

    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 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. :)))))~

    What's with the polar reviews here? A friend of mine recommended this place & their spicy ranch. Any Yelp elites care to chime in?

    Great question, I’d look at what time most negative posts occur. I think you’ll see that a large portion of them come after 2am. Being open late is definitely a part of Cosmo’s. However, it’s not always easy to please everyone late night.

    Don’t See Your Question? Ask Away!

    I'd heard that this local French crepe place was good and because of transportation issues had not…read moremanaged to get here until now. But I am glad we had time today and went shortly after they opened for brunch and really enjoyed ourselves. We decided to share one savory crepe and one sweet. They are very large yet delicate and we barely finished them. Our savory was the Parisian and the sweet was the classic lemon. They were perfect in every way. Order at the counter when you arrive and choose a seat in the dining area. It's classic white walls with art and wood tabletops and metal classic cafe chairs. The food was excellent, the French chef owner made the crepes and delivered them to the table. We had picked up our drinks as we paid before choosing a table. It's usually been full when I've seen pictures in the past but it was a very cold day and students at CU as well as other families just getting back from the holiday season. They also offer Build Your Own Crepe and we probably will next time. For a sweet crepe next time I would do one with Nutella but without any banana as many of the standard choices had. For savory next time I would take the Normandy. We chose quickly today as a line started forming behind us. I had looked online at the menu though my husband had not had time. A plan would be good. It appeared that the counter staff may also be family. It is such a welcoming place with really good food, not found elsewhere in Boulder. And very good pricing for quality and portion size. They opened in an unusual little spot, almost downtown but not quite, in the stretch along Broadway between CU and the Pearl St Mall. They have a small parking access to 4 shared spaces with the shop next door to it and the access is on Arapahoe. If you are staying at the large new hotels on the Hill it's an easy walk, the equivalent of one long block. If you know Boulder well and need to easily park, there is paid parking in the library lot across Broadway and an easy flat walk both ways.
