Quote El Barbudo="El Barbudo"I'm being pedantic, I know, but there are many "genuine" Indian restaurants in the UK, especially in London.
Granted, the other 98% (my sweeping guess) aren't "genuine" at all.
But hey, if that's what people like, where's the problem?'"
I know of a fairly authentically Bengali restaurant in Leeds, which granted only does the really authentic stuff on special nights set up for the purpose. It must be said that the differences from the normal fare aren't as vast as some people would have you believe.
Generally, eating Indian food in the UK is quite similar to eating Italian in New York. There's a cuisine which has formed by the influences of a country of origin (with lots of regional variations and traditions), and then both developed (food does that you know, in all cultures) in relative isolation from that country of origin within an ex-pat community, and also been influenced and altrered by the pre-existing culinary culture in the new country.
You could then call it "UK Indian" if you wanted to be a pedant, but to dismiss it as "inauthentic" or not "genuine" is over-simplistic.
