We were in Boulder, and searched Happy Cow for a good vegan restaurant option. The review of the Friday vegan buffet was great, but it was a Monday. We decided to give it a shot, and see what regular vegan menu items they had. Well, big disappointment. Basically, none! I asked our server if they could make something for us. She came back and told us "No, the vegan cheeses, etc. are frozen." Apparently, they are only feeding vegans on Fridays. Other days, we're out of luck. We left and found a great Japanese restaurant with many vegan options. See my review of Japango on Pearl St. As much as I love the idea of a vegan buffet, I think Jill's is not as vegan friendly as they pretend.
Cons: Not vegan friendly every day, No regular vegan menu items
