Gayot "The neighborhood is surrounded by an excellent selection of bars and restaurants and is very close to both Berkley Square and Hyde Park"
Jetsetter "Just doors away is the Curzon Mayfair Cinema, London's swankiest picture house, complete with royal box and wine bar"
Oyster "The hotel is surrounded by a choice of restaurants, but
also has one on-site as well as a lounge bar and a small, simple fitness center with modern equipment"
Star Service "The adjoining open-plan room harbors both the lounge and a restaurant, where soaring windows flood the dining area with natural light, though dinners are a dim affair, almost too dark to read a menu"
