There's plenty around London but they don't sell the stottie (it's a type of bread) which is one of the things Greggs is famous for in the north east. As Greggs is a Newcastle based company I thought they would have had stotties in all their stores (perhaps they tried it and they weren't popular).

Looking at what they sell in Scotland it looks like they vary their range based on region. Never been to Greggs for years after I discovered you can't get stotties in the south. When I'm visiting the family me mam always has some in the house anyway
