3. Lexington Candy Shop

Lexington Candy Shop is one of New York’s most recognizable and much-loved luncheonettes still in operation. Located on 1226 Lexington Ave., the corner restaurant’s largely unaltered vintage storefront harkens back to the New York City of yore. You can take a seat at one of their red pleather stools and enjoy a classic malted milkshake or butter burger for a decent price. Unlike some of the other low-key eateries on this list, Lexington Candy Shop accepts credit cards.
