Leila McAlister's grocery shop and café off Arnold Circus, Shoreditch. You can find the best of everything, from jars of horseradish to eggs and croissants.
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
It is a music store in Brick Lane. You can spend there the perfect Sunday afternoon, listening to lot of new good music, thumbing through cool books while relaxing in their café. Oh, and the Rough trade photo-booth is a must if you go there!
