Should I make a special theme with an all vegetarian menu?

I have a few vegetarian friends. I know they’d love it but as a meat-lover it is not going to be easy. May take a lot of effort. And we all know the drill: add mushrooms, throw in a couple of nuts and lather with cheese and all is fine. Well that’s just too easy. So if I am going to do it, I want to do it right. Because I can (or should be able to, at least)!
