Cheap Eats In Edinburgh, Scotland Under 10 USD - Updated 2021
"Devotees of the pork sandwich will flock to Edinburgh’s Oink; although the menu may not be especially broad, they’re exceptionally good at what they do. A hog roast on a roll, (small, medium or large), with a choice of stuffings and toppings, and with a drink on the side, will cost you 9 USD at the most. The optional stuffings are either classic Sage and Onion or, for a more Scottish taste, you can add haggis."
