Also known as 'the bar with no name', this tiny establishment may be nothing much to look at, but it has a stellar reputation for its cocktails (£11). The seasonal drinks menu is steeped in ambitious flavours and blends, with classic drinks for more conservative palates. Hard to find a seat at the best of times, so make sure you book ahead.
Also runs two-hour cocktail masterclasses (£50) from 2pm at the weekend.
