Here are three of the not-available-in-most-of-the-US-unless-you-buy
them-on-the-internet foodstuffs I tasted while in Scotland.

1. Burt's smoked streaky bacon crisps were okay, just not bacon-y enough for my taste.
2. McVitie's milk chocolate digestive biscuits are an old favorite- I love them and they are even better dipped into hot tea. It's actually good that it's hard to find in the States, or I'd eat way too many of them.
3. And then there is IRN-BRU, Scotland's favorite (non-alcoholic) beverage. Do I like it? I don't know, I just don't know. The only thing I do know is that it is not good warm, not good at all.
