I haven't been off my upstate NY college campus since I got here in August, and I'm about to start bouncing off the walls like a self-propelled missile if I don't get the heck outta here and latch my jaws around some food that didn't come from a dining hall. To that end, I'm hoping to go into NYC for a day trip pretty soon, and I've been craving a really good veggie burger.

Please recommend me a place to get one!!!! (Not made with portobello mushrooms, please.) Ideally cheap and friendly towards single diners.
