Last year my BIL (Dan's younger sis was my HS locker partner, we are still friends!), who is British, took his "British Foods" store to the Ren Fest in Des Moines. He had a store selling dry goods (Heinz Beans, biscuits, jams, etc), and then a food stand with curries, bangers/mash, etc. First curry I ever ate and it was outstanding!
Anyway SIL and I worked the dry goods tent, and had to wear period costumes. It was actually quite fun.
