Adored by Madonna, the super-stylish Blue Bar-- located by the lobby of the Berkeley hotel-- is oft considered one of London's best bars. Designed by David Collins, the 50-seat bar is distinguished by the black crocodile print leather floor, white onyx bar, sunken seat area, and, most of all, by the gorgeous color of the room, which the designer has dubbed "Lutyens Blue." The drinks list includes a wide selection of Champagnes, original and contemporary cocktails, wine by the glass, and over 50 different whiskies. (There's even a Grape and Smoke menu for guests to pair cigars with carefully chosen wines.) In addition to the olives, caramelized nuts, and tasty nibbles which accompany each drink order, guests also enjoy the Asian-inspired tapas menu, which includes delicate and delicious dishes like queenie scallops with wasabi and lime vinaigrette, char smoked salmon with basil and yogurt, lime leaf and chicken on coconut crisp and citrus coulis rice paper, and nori wrapped vegetable rolls.
