This Upper East Side burger joint has been faithfully flipping patties since the 1970s, and it’s still consistently rated one of the best burgers in New York. (A West Village location opened in 2015.) The no-frills pub has a crowded dining room and cheap prices, which is good, since it’s cash only. For a juicy burger that’s under $10, plus fries and other great bar food, it can’t be beat. Go for lunch, dinner or an after-hours bite—the kitchen is open until 2am.
