London is so vast I am forever coming across new hidden gems. Walking around the streets and getting lost is the best way to find London's best kept secrets.

Designed by Wells Coates, the Isokon Building opened in 1934 and was the first apartment block to be built using reinforced concrete. The Isokon Gallery is open at weekends telling the story of the Isokon building, the pioneering modern apartment block as an experiment in new ways of urban living.

Appreciate the 'bar hidden away behind a bookcase' thing is pretty naff but the cocktails here are unreal (try the Hot and Cold), and it's inside Milroy's Soho, one of the most legendary spirits stores in the city

I can't pass without dropping in, Orcs Nest is a small independent boardgame, D&D etc store that's been around forever(1987)... and has the best logo. Good selection of games for younger kids too.

Bowling alleys, karaoke rooms, pool tables, arcade machines, this is basically Feltham Bowl for adults. Part of the holy trinity along with Max's Sandwich Shop and The Faltering Fullback
