In a stylish speakeasy bar in the heart of Shoreditch lies a secret room. Behind an opulent floor to ceiling looking glass you’ll step into a wonderfully eccentric, secret world inspired by Lewis Carrol’s Alice in Wonderland.

3. Barts

Barts

Set in the 1920s prohibition era, Bart’s is run by ‘Chicago gangsters’ involved in illicit bootlegging activity. To keep their operation secret, the bar is located in a Sloane Avenue apartment, dressed up as the residence of Uncle Bart.

The decor could be described as junk-shop chic with chintz wallpaper, stuffed animal heads and cuckoo clocks, it’s certainly eccentric. There’s also an extensive list of cocktails, some served in top hats and teapots, by bartenders in 1920s get-up.

Don't like what you're wearing that night? Head to the trunk and pick something to wear from their fancy dress.

Find it behind a jade door in Chinatown, when the amber light is on, you can go in.

Spread over three floors of a townhouse, a labyrinth of rooms make up this intriguing venue. East meets West in this Chinese-influenced bar, you can sit in retro armchairs as the smell of incense drifts by, try dim sum in the Dining Room and mysterious concoctions in the Apothecary Bar.

A set of fairy lights adorning the staircase down to the venue are the only indicator that The Lucky Pig exists. Once you’ve found it, hidden down a back street in Fitzrovia, you’ll be greeted by a 1920s style bar with exposed brickwork, shabby-chic decoration and cosy corners.
