I love how much you are aware of the changing seasons out of the city; there are numerous beautiful forests around Hertfordshire to go for a run, a walk or have a picnic. One of the best destinations for a day out from London might be Northaw Great Wood. The main entrance is located on the Ridgeway, the B157 from Cuffley to Brookman's Park.
This is the most genuine and unpretentious pub I have visited in London. The Palm Tree is on the east London canal outside of Victoria Park. You won't find it unless you know it's there. (And now you know!)
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.
Lisson Gallery is one of the most influential and longest-running international contemporary art galleries in the world. Since being founded in 1967 by Nicholas Logsdail, it has championed the careers of artists who have transformed the way art was made and presented.
