They dont like UK food in the main,I have been to loads of peoples houses,Pakistanis,indians,thai,pinoy,sri-lankan,indonesian loads of chinese,in the main those residing in the UK tend to cook foods indiginous to their country of origin,dont you remember the "Goodness-gracious-me" sketch where the indian tourists to the UK went for a beer and afterwards went to the typical english restaurant and asked for the blandest dish on the menu,it was a skit of the typical english visiting an indian and asking for the hottest afterburner curry,most of our food is thought of as bland.
