You had me at \"biscuit.\"\n\nSo Burton's Foods \"is the second largest biscuit manufacturer in the UK\" with bakeries around the UK, including in Edinburgh, Scotland.\n\nI don't know if they offer proper tours of their baking facilities, but you can skip the tour and get to the goodies: an outlet store that offers sacks of defective biscuits (maybe deformed, or maybe they contain too much of a certain filling) at cheap cheap prices. \n\nIt's not the most fanciest of outlets (you can maybe fit 5-6 people in the store), but you go to the counter, see what's available, order and pay. That's it.\n\nI was able to walk out with a decent sized sack of Toffee Filled Biscuits with Milk Chocolate, a retail package of Cadbury Digestives and Bisca My Choice biscuits for under \u00a35.\n\nThe advantage is that you know that these are super fresh and direct from the factory.\n\nThe Toffee Filled Biscuits were delightful to eat and were so good I had to stop after the 7th one.\n\nIf you're in Edinburgh, take a visit to the factory outlet (call for operating hours).
