I think its pretty good.....better than almost anything I ever had in India for sure (of course it costs a hell of a lot more too).
Personally I'd say you can find great Indian food all over the UK..Manchester or Bradford have some amazing places.A lot cheaper than London too.
If you are lucky you can find a really good Indian restaurant in the most unexpected places..last year I had a curry in Phnom Penh that was outstanding!
