Inside trendy Hotel Monaco, Poste woos diners with a towering skylighted space that until 1901 was the General Post Office. Homing in on Modern American brasserie fare, chef Kyoo Eom conjures up such satisfying dishes as gnocchi in vermouth cream sauce and steak frites. In season, soft-shell crabs are not to be missed. For dessert there's the graceful chocolate semifreddo served with raspberries and a floral compote. In warmer months the neoclassical courtyard is a serene spot for fruit-infused cocktails and brunch, with an ample build-your-own Bloody Mary bar that's a steal at $10. Year-round, the lively bar inside attracts scenesters with booths on raised platforms.
