With its hip, relaxed vibe, too-cool crowd and dramatic central fireplace, Olsen could easily be located in the frosty climes of Scandinavia. Chef German Martitegui’s dishes are limited but inspired, and the vodka selection – over 60 – is superlative. Luxuriate with an exotic cocktail in the lovely front garden, or try the popular Sunday brunch. Limited menu between lunch and dinner.
