Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it’s packed then The Red Lion is just up the road.
The Premises is cozy café attached to a recording studio in Hackney (frequented by Nina Simone, Al Green and Jarvis Cocker over the years.) Lovely people serve up tasty breakfasts and Turkish food in the evening.
The Party Superstore was/is my absolute favourite London shop until it was bizarrely attacked and gutted during the summer London riots. They have been since adopted as a concession by the local Debenhams but you can still savour the full delights of the products and nonsense on line.
