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.
This independent cinema near Angel in North London is over 100 years old and has had several lives including hosting early Sex Pistol gigs. It now serves as my favourite place to watch films (along with the Rio in Dalson).
Also the Queens back garden, these beautiful grounds are great for a Sunday stroll to see the pelicans or to feed the squirrels. Duck Island Cottage is worth a look too, a idyllic little cottage situated in the grounds which was specially built as the bird keepers home.
