Bon Vino 35

You're walking past the railway arches near London Bridge, and you spot this place—unpretentious frontage, but inside it's a proper operation. The selection's serious without being snobbish: you'll find affordable everyday bottles sitting alongside harder-to-find stuff that makes you think. The team know the difference between someone after a reliable Côtes du Rhône and someone hunting for something specific. They do events, tastings, that sort of thing, so it's worth checking what's on. This is the kind of place locals actually use, not somewhere you'd wander into by accident.
