Would be OK, if more stalls were doing samples.. Cheapest thing I saw were bags of popcorn, and sausage rolls (each £2). Pub prices or higher, or drinks.
Glad I got some free tickets, as food rather dear inside, and hardly any free samples left too.. If I'd paid £13 a pop, would be most disappointed.
Some free demo's (book early, or arrival) and music, though.
