There's a Burger King around the corner from here, but every time I check them they don't have much for vegetarians. McDonald's is even worse, they put meat on their salads even. Last time I saw it, anyway. I sometimes, rarely, eat their fish fillet which is pretty nasty as well, but what can you do.
I've recently taken to buy from one of the pizza stands instead of McD. It's cheaper, tastes better, and they have veggie pizza. Win-win in my book.
