Hilton Brooklyn guests are in for a treat at the hotel’s chic Black Walnut restaurant and lounge. Chef Rob Newton, originally from Arkansas, is not just one of Brooklyn’s best Southern chefs; he’s one of the borough’s best chefs, period. His New American outlook means stone-ground grits have an Italian, cacio e pepe twist. Organic chicken is soaked in coconut milk and spiked with chili oil. Those looking for comfort food might gravitate toward the delicious burger. The low-lit, relaxed seating in the dining area broadens the appeal well beyond that of a typical hotel restaurant.
