Hopefully not derailing, but this is a very narrow view of Scottish cuisine.
Scotland has some of the finest raw ingredients in the UK, arguably the world in certain niche areas, and the quality of Scottish food is actually incredibly good, if you go looking for it.
Yeah, there are dodgy fish & chip shops, chicken outlets and lacklustre pub fare just like everywhere else, but there are also incredible restaurants and cafes based around local ingredients as well a diverse range of global food trends.
I can understand why people might not want to live in Scotland, each to their own, but criticising the food is, I think, to fall back on cliche.
