Burgers on the cheap, without stinting on ingredients, is the mission at this clubby little hangout. To maintain quality control, the beef is ground in-house. Sliders start at just $2 (with cheese and onions) and can be topped with ketchup, chipotle ketchup, barbecue sauce or super-spicy roasted jalapeño sauce. Mark is ideal for a visit before or after a drinking bout at one of the East Village's innumerable watering holes—or you can stay here and indulge in the beers on tap. While it's short-order cooking, the dark lighting and bar make it more of a date place than your average fast-food joint.
