Perpetually busy, the pint-sized Lamb & Flag is full of charm and history: there's been a public house here since at least 1772, when it was known as the Cooper's Arms and infamous for staging bare-knuckle boxing matches. Rain or shine, you’ll have to elbow your way through the merry crowd drinking outside to get to the bar.

　　The main entrance is at the top of tiny, cobbled Rose St, but it's also accessible from the backstreet donkey path called Lazenby Ct that will temporarily transport you back to Dickensian London. Watch your head.
