i'm a san francisco hound headed for a week in london. i'm not so much looking for specific restaurant recommendations, but for ethnic districts through which i might gastronomically stroll. i'm particularly interested in south asian, middle eastern and african, but other tips would be appreciated also.
the ideal form of reply would be something like: 'the biggest nigerian community is just west of the xxxx tube station, and they have a street market there saturday mornings'
if any of you will happen to be in london over the next week or so, feel free to join.
