The best "Chinese" restaurant I ever went to was a fish'n'chip shop in Scotland. It was owned and run by a Chinese family and holy crap! They made the best fish'n'chips I have ever had anywhere, before or since.
Well I say it's a restaurant, but it's a takeaway.
You get so-called "Chinese chip shops", or "Chinese chippies", in Britain that are run by Chinese people and in them you can get some Chinese food like prawn fried rice as well as traditional British chippy food, like fish and chips, mushy peas, puddings (steak and kidney in a suet pastry), pies. Sue's Chippy on Rishton Lane is like that.
I often go in after work late at night and order prawn fried rice or pudding, chips, peas and gravy. She works there on her own and you can see into her living room in the back through a doorway. She's often got Have I Got News For You on the TV, with the volume turned down and English subtitles on, and she has Chinese music playing. She's closed for several weeks now until the 11th April so I'm assuming she's gone visiting family in China or something.
The Lucky Star on Deane Road is a proper Chinese takeaway, though, with just Chinese food.
