I'm leaving soon for a ten-day trip to London and while I have a fairly well-researched itinerary of British restaurants, I'd like to round it out with some other cuisines. I have lots to choose from at home when it comes to foreign foods, and I've been fortunate enough to sample enough continental European cuisines in their home countries, so I'm particularly interested in anything that has morphed into something new since migrating to the UK.
Also of interest would be foods from immigrant communities that aren't found in many other Western cities. For what it's worth, I live in San Francisco and will be staying in Shoreditch (on that note, does anyone know if London Vietnamese is significantly different from what I'd be used to?). I'm willing to travel anywhere accessible by public transport.
I also have a particular question about Spanish food. There are few things on earth that I love more, and I understand it's big in London, but given that I've spent some time in Spain is it still necessary for me to try the British interpretation?
Non-British restaurants currently on my list:
Honey and Co.
Brick Lane Beigel Bake
(my parents are Israeli, hence my interest in the latter three)
Thanks in advance!
