I'd have to agree, the food is better in Scotland! I can't remember having a bad, or even average, meal up there. I had the best home made veggie sausages in a cafe in Glasgow, served with apple mash, it was so tasty. Wish I could remember the name of the cafe! Great curries in Glasgow and Edinburgh too.
Other memorable food while travelling: eating koshary in Egypt (sounds horrible, tastes wonderful mixture of macaroni, rice, lentils, tomatoes, lemon juice, topped with crispy onions); pili pili fish in Kenya; fantastic seafood in New Zealand (incl. the wonderful Polynesian fish marinated in lemon and coconut cream); awesome mezze in Dubai and Khartoum;
