London - Shoreditch and Camden Town
Camden Town is full with second hand shops and music shops. It's one of London more 'alternative' neighbourhoods and definitely worth a visit. Also visit the Camden Market for great finds. If you get hungry I can recommend Honest Burger. Nearest underground station is Camden Town.
Shoreditch is definitely a hipster place. You can expect 100% locals, no tourists. It's also a great place for street food: Boxpark, Pump Street Foodmarket or Dinerama to name a few places. There is no underground to Shoreditch but you can go there by Overground. Get off at Shoreditch High Street or Old Street.
