Zenkichi is a hugely popular and stylish Japanese restaurant on a quiet street just off Friedrichstrasse. Descend the steps and discover a traditionally decorated dining area with floor lanterns, dark wood tables and bamboo-curtained booths, providing a little slice of Tokyo in one of Europe’s great capitals. Vegetarians and fish lovers are well catered for here: grilled Saikyo black cod, Hokkaido scallops and seasonal vegetable tempura are excellent, or try a tasting menu for the full experience. The sake list here is the best in the city – go for the connoisseurs’ tasting selection.
