SOAS university has a small gallery space dedicated to exhibitions about Asia, Africa and the Middle East. There's a small but beautiful Japanese zen garden on the rooftop (currently closed for refurbishment)
My all-time favourite place. Whitewashed ex-smokehouse where Fergus Henderson pioneered the resurgent interest in offal dishes. The restaurant is brilliantly unfussy, retaining lots of the smokehouse’s original features, and the food very British, making St. JOHN something of a London institution. The restaurant has a winery and bakery.
Eccentric and surprising house and museum of architect Sir John Soane. Mostly unchanged since his death over 180 years ago, it is full of atmosphere. Also have spotlit, late night openings.
