London on the Inside and Cherry Cola Rooftop Party

Four floors up from the streets of Dalston, the ever-popular Roof Park offers good views and even better cocktails. Take advantage at this cheap bank holiday party, with all-day indie DJs and guitar-twanging surf-rockers Men’s Adventures live. Advance booking is only a fiver, making this a no-brainer as long as you have a head for heights. Tickets are valid until 6pm, so if you get there after that then prepare to queue.
