6. Off-the-Menu Burger, Gramercy Tavern

In 1994, famed restaurateur Danny Meyer opened the Gramercy Tavern, located on 42 E 20th Street in the Flatiron District. It’s situated in a historic landmark building, designed by Bentel & Bentel, and features murals by artist Robert Kushner and colorful floral arrangements by Roberta Bendavid.

Since it was established over two decades ago, the much beloved restaurant has specialized in contemporary American cuisine, offering a seasonal menu built upon a relationship with local farms and purveyors. While you can opt for dishes like grilled pork and smoked duck, Gramercy Tavern also offers an off-the-menu burger, made from beef that is freshly butchered and ground in-house, and served with a fresh-baked bun, cheddar cheese, Bibb lettuce, raw onions and several condiments. According to Eater New York, the restaurant used to only offer 20 of these a night, but it has since increased its production (likely due to demand).
