Having lived there for a spell, I can sympathize with your question, but one thing the Brits do excel at, is fish and chips. I thought I'd had fish and chips before living in England, but the first time I tried them there, I realized I'd been had.
Let me tell you, there ain't nothin' like a hot serving of authentic British fish and chips when you're walking home from the pub on a cold British night.
I was in England 88-91
First experience with Brit Fish and Chips was I took a big bite of the sandwich and searing oil squirted out onto both sides of my mouth. I had a big burn sore on both sides of my mouth for days. I looked like the Joker from Batman.
Never ate at THAT place again. Best F&C I ever had was at a little pub outside RAF Sculthorpe near Kings Lynn. Yum!
