Bamboo Door

You'll descend into something properly atmospheric here—exposed brick, dim lighting, the kind of place that feels like a proper discovery even though it's right in the city centre. Bamboo Door takes cocktails seriously without the pretension, which is refreshing given how easy it is for bars around Leopold Street to tip into trying-too-hard territory. The drinks aren't cheap (expect to pay £12-16 per cocktail), but they're genuinely considered—you're getting technique and quality spirits, not Instagram bait. It's the sort of spot where you can actually have a conversation, and the bartenders seem genuinely interested in what you're after rather than just executing orders.
