Ya, they're all over the place now, all the new Shell stations around here have a Cinnabon, Sbarro, Greg's, or Pizza Hut inside.
The Cinnabons seem to close up fast, no one want to pay £3.50 for a bun. You can get a Tesco meal deal for that 😅
I know Sbarro is the McDonald's of pizza, but it's not too bad, fiver for a big slice of pepperoni and a soda.
