The veggie burger was once a sad food item. It was tossed onto the menu at every kind of restaurant from suburban chains to upscale steak houses to trendy gastropubs almost as an afterthought, a bare nod to the idea that some of these weirdo nonmeaters might come in and we gotta give 'em something. As food has become more introspective and the American public began to seek vittles beyond Sysco meals, the veggie burger evolved. Tap 42 does a particularly creative take: no fake meat or boring beans, the patty is basically a large falafel made from ground chickpeas and fried to crispy goodness. It is then topped with roasted red-pepper tzatziki (a yogurt-based condiment), lettuce, tomato, and onion. You don't have to be a vegetarian to enjoy a sandwich like that.
