José Andrés's two-Michelin-star Penn Quarter tasting room is the kind of dining experience that exists almost nowhere else in America — twelve seats, a 20+ course menu of liquid nitrogen, smoke, and elBulli-trained playfulness, performed by chefs at counter-height eye level. Drinks at the connected Barmini lounge between courses if you want. Expensive in a way that earns it. For diners who want a meal that's also a performance.
