I've lived in Fort Collins for over 15 years and I've gotten chicken mixed in with my "vegan" dishes at least six times at Rasta Pasta. They have some limited vegan options--will sub tofu for meat--but I'm extremely wary of eating here due to past experience. I've also been told conflicting things by different staff members regarding ingredients, how something is cooked, whether it is vegan, etc. It remains popular with many locals (which is why I've been dragged back) and has unique pasta dishes, but double-check your plate before digging in if you go.
Cons: Sloppy kitchen, Staff not knowledgeable about vegans, Frequent kitchen errors--meat in food
