It doesn't have to be food. It can be anything. What do you wish existed in your area?
I'm not that big a fan of roast dinners, I enjoy them just a few times of year but I wish that my area had the roast shops(I don't know what they're officially called) that they have in Yorkshire. I'd love to be able to get a turkey or roast pork roll with apple sauce or even better a bag of hot crackling pieces.
I'd also rather like to have a good fudge shop here.
And more second hand and new book shops. When I go to certain parts of England there are so many compared with her. Edinburgh and Wigtown aside. I love charity shops but it isn't quite the same.
