Everything about Whisper Sister screams speakeasy - the lack of signage, the small gold plaque on the door with a number to call to be let in, and a doorman that greets you and leads you down the red carpeted stairs. There's bar, the 'living room', with a few tables, and then the large circular room with booth-like seating and smaller glass tables. Reservations are needed for every area, except for the bar, and if you get there by 21-22, you should still be able to find a seat. Try a speciality cocktail or some craft alcohol. We quite liked the G&T - Gin & Tea with matcha tea and creme de cacao.
