So, inspired by my recent trip to Chile, I thought I would make a map of where it is easy/hard to be a vegetarian. It ranges from:
Amazing: India, Italy and Thailand, oh my!
Good: you don't need to check the menu, every place will have a couple of decent vegetarian options
Okay: you might need to search a bit, but you are not going to go hungry and there are occasional gems
Poor: waiters will look at you funny, but the cook will try to make you an omlet or something
Bad: yeah, expect to have a few meals based around fries and beer. Waiters are just going to say "no".
Food desert: desperately looking for a Subway or pizza place, you'll end up appreciating airline food at the end
Note: a lot of these places can flip dramatically if you eat fish, most notably Spain, Indonesia and Japan
