The term “casual elegance” gets thrown around a lot, but it applies at this bar, the lounge off the lobby of the St. Regis hotel and next to the restaurant Adour. Velvet chairs arranged around small tables and a fireplace give the room an inviting charm, but the vaulted ceilings and grand windows impart an air of importance. Some of the specialty drinks are on the sweeter side, so a classic cocktail is a safe bet.
