The Luggage Room

You'll descend into something properly atmospheric here—the kind of basement bar that makes you feel like you've stumbled onto something the rest of London hasn't quite cottoned on to yet. The Luggage Room, tucked under Grosvenor Square in Mayfair, channels that old-school speakeasy energy without the pretension that sometimes comes with these things. The drinks are genuinely excellent, the sort of place where the bartenders actually know what they're doing and won't just sling you a vodka soda. It's got that intimate, low-lit vibe that makes you want to stay longer than you planned.
