Underbelly Festival Southbank
From April until the end of September, Underbelly Festival Southbank is an amazing pop-up festival with some of the best circus, comedy, cabaret and family fun.
The grown ups can get an after work drink in one of London's largest outdoor bars and there's international street food to keep appetites at bay.
Shows are short at an hour long (mostly) and most are under £20 so very affordable both time wise and pocket wise.
