In Uxbridge growing up there was a commericial lot that was a cursed venue for US chains trying to make it over here.
First it was a Taco Bell. Literally in like 4 years I never saw anyone go in there. Saturday afternoon at 2pm the Mc Donald's across the street would have a queue down the road and Taco Bell would be deserted. Not even one person every thought "Hey fuck it, I'll give it a go"
Then it became a Wendy's. I was sceptical for so long - looked like a cheap mix of Mc Donald's and Wimpy. But a mate went on holiday to the States and came back raving about it. We went and we were sold. Amazing A SQUARE BURGER. I was quite sad when they closed. I had a Wendy's in Atalanta airport a couple of years ago - they had Dr Pepper on tap.
Then it became a Burger King. BK has obviously done pretty well, but it failed because there was, without exadgeration, a Burger King about 15 seconds walk away.
Then it became a KFC, and has been ever since.
Sorry this is a disaster of a thread. I just miss Wendys. And it made me think, what other US brands/chains have chanced their arm and failed
