As jimi_d said, Wal Mart is represented here by Asda. Although they don't seem to be growing that much at the moment, as they still have to face the vast ever growing behemoth that is Tescos. And Asda have bloody annoying adverts.
I like the idea of buying beer at a fast food place, even if it is crap beer. I was unaware Wimpy's were still going (main marketing point- proper cutlery and crockery!) until I drove past one the other day. It was like a blast from the past.
Like Nandos too, and am also quite fond of Mamma Amalfis, an Italian restaurant chain here. Are they anywhere else? They do a very good calzone.
