K Bar

You'll find yourself in the polished confines of The Kensington Hotel's cocktail bar, where the vibe is decidedly grown-up without being stuffy. The bartenders here actually know what they're doing—no faffing about with gimmicks, just proper technique and thoughtful spirit selection. It's the sort of place you slip into after work or before dinner, surrounded by South Kensington's quietly moneyed crowd, though you won't feel out of place if you're just after a really good martini.
