My family is traveling to Prague and then driving south to Vienna this coming summer. My 17 year old daughter is vegetarian (not vegan) though cheese is not a big favorite for her. How available are (no matter how simple) vegetarian meals? If she has to eat salads every night so be it, but I'd like to know if we need to bring a stash of protein bars! We're not looking necessarily for vegetarian restaurants, as our time will be tight and we'll probably need to make due with whatever is close by. (she does not eat fish) Thanks!
