DC and I are visiting a friend between Christmas and New Year, staying overnight for 1 night. I'd like to bring a little gift to say thank you for hosting us; I was thinking some kind of treat-food from Waitrose or M&S or somewhere. I'm normally an Aldi girl (she definitely isn't!) so I'm not familiar with what's good / appropriate from a "nicer" shop. Any recommendations? Doesn't have to be food if you have a different suggestion!
