Raw cafe in central Prague. I am definitely NOT a vegetarian, but when I feel like I want to be a good boy, I go here. It's close to my office and is also very popular with colleagues. It's also a great place to satisfy the office 4pm need for CAKE
If you are a vegetarian in Prague, don't be intimidated by the seemingly infinite and unavoidable sight and smells of roasted pigs... There are also a few excellent vegetarian restaurants in Prague, this one being my favourite.
