Haven't been here in a few yrs it amazing pizza but the only thing I don't like is that they change there hours like on a daily basis would love to stop by during the day an get some pizza for lunch some time while I'm on a lunch break ... (need to have decent hrs it's crazy they are only open from 5pm to midnight ) that's the only reason I haven't left 5stars other then that I would love to leave 5 stars

I remember when John first opened in 2002. Being from the east coast I am pretty picky about pizza. It's a CU staple. Going on 20 years they are doing something right.

Cosmos hits the spot every time. A massive slice with a cup of spicy ranch is what you have to get. The pizza is well cooked and flavorful, and the spicy ranch is such an interesting sauce to dip pizza in, but works so well. They're quick and nice, and cosmos stays open late night. I suggest going in person as opposed to ordering if possible. Awesome pizza place. (from @tastessky on Instagram)

Throughly enjoyed this pizza place! This was my first time having it and I was so satisfied. I did not think two slices would fill me up but I was wrong. They are massive and greatly worth the price.Also, the place has a fantastic vibe! The use of colors was a great mood. They were also playing Shrek on TV so one can never go wrong with that.Would go again!

Being from Nj, I'm pretty picky about pizza but Cosmo's is pretty good. Their spicy ranch sauce is a must.

We tried a few slices to go and really enjoyed the pizza. There were quite a few folks waiting but the line went fast and the staff were all quite friendly. We'll be back for another slice!

Wow. Pretty bad calzones. Ordered two and a salad. Both calzones were undercooked and the salad was both spicy and flavorless.Just weird. Usually I give places 2 tries, but I can't stomach a 2nd attempt. Yuck.

Great pizza in Boulder. The pizza is consistently great. Just don't dine in. Cosmos is not known for the ambiance. The atmosphere at Cosmos is not great, but grab a slice and go outside to enjoy the Colorado sunshine. Take out or delivery makes for a great meal.

Cosmos just lost our business. There are plenty of other friendly pizza joints in the area that know how to treat their customers and that have fresh pizza and a clean restaurant. The guy that was working in there today was awful, I will not be setting foot in that store ever again.
