Don't have time to google for recipes, but have a look for the following:
Cock a leekie soup
Cullen skink (smoked haddock and potato soup)
Scotch broth
Salmon and herring are both traditional, as are venison, rabbit and steak.
Deserts can be shortbread based, someone said cranachan earlier which is delish. Gingerbread or anything butterscotch would do as well. PMSL butterscotch Angel Delight
If they aren't full after that, then there is always tablet or puff candy.
Drinks wise, there are a couple of scottish wineries who make fruit wines (yummy ones at that) try googling Moniack winery or Cairn O' Mohr. They do mail order I think. And of course there is whisky and also something a bit like Baileys, erm can't remember name, something like Heather Cream.
Oh, and of course haggis!
