Be At One - Covent Garden Lyceum

You're on Wellington Street in Covent Garden, dodging the theatre crowds and souvenir shops, when you duck into Be At One. The vibe is properly buzzy without feeling forced—locals and tourists mixing naturally, decent music that doesn't assault you, and staff who actually care about what they're pouring. This place takes cocktails seriously (their classics are spot-on) but won't make you feel like an idiot if you just want a G&T. The space has character too; it's got that theatrical neighbourhood energy without being precious about it.
