Park Burger's housemade veggie patty is a mash-up of grains that's smashed on the grill — giving it the juicy, messy characteristics of a smashburger, but without the beef. The burgers are served in wire baskets lined with paper and topped with lettuce, tomato, onion and a special burger sauce (which tastes a lot like Thousand Island dressing), and from there it's up to you. Other vegetarian topping options include several kinds of cheese, a fried egg, guacamole, mushrooms, onions and jalapeños — and those watching their carb intakes can even order the burger on a whole-wheat bun for an additional charge. (Fair warning: It's not vegan.) Served with Park Burger's shoestring sweet-potato or regular fries (crispy and sprinkled with coarse salt), this is one veggie burger that doesn't taste like a compromise.
