Housed within The Benjamin hotel at 557 Lexington Avenue, The National Bar & Dining Rooms presented Chef Geoffrey Zakarian’s refined take on the American brasserie—serving breakfast through dinner in a sleek, Art Deco–influenced space of white tile, brass accents, leather banquettes, and a lively copper-topped bar. The menu centered on elevated bistro classics—think oysters on the half shell, steak frites, a signature dry-aged burger, roast chicken, seasonal pastas, and vegetable-forward sides—alongside a focused wine list and a serious craft-cocktail program. Private dining was a standout, with a semi-private mezzanine overlooking the main room and an intimate private dining room well-suited to executive dinners, boardroom-style breakfasts, showers, and milestone celebrations. Event menus typically offered customizable prix-fixe formats, passed hors d’oeuvres, chef’s stations, and thoughtful accommodations for dietary needs. Reviews consistently highlighted the restaurant’s urbane but comfortable vibe, professional service, and its popularity for business lunches, after-work cocktails, and weekend brunch.
