The Thai food scene in London is in an incredible place right now, with the likes of The Smoking Goat, Som Saa, The Begging Bowl and Farang all offering an experimental and delicious take on the cuisine. I'm focusing on the later a) because it's my local and b) because it's helmed by Seb Holmes, who's also cheffed at those others mentioned, and has managed to bring the best of all of them to Farang. Oh and c) the Gai Prik is probably the tastiest dish in London
The best thing about any charity shop is that you never know what you are going to find. I have a well tested route around London that includes all of my favourite charity shops. This Oxfam has a great selection of books and often turns up some interesting clothes too.
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)
