So we have travelled to the higher latitudes to the wonderful city of Edinburgh, and we are staying with our friends Tancred and Evelyn. Edinburgh has been the most laid-back and relaxing city we've been to so far. We've seen Edinburgh Castle, Mary King's Close, lots of Scottish Baronial architecture and had a walk round Holyrood Park (though we haven't managed to climb Arthur's Seat yet). And we have indulged in the local gourmet delight that is the deep-fried Mars bar: a unique culinary experience indeed!
