I've actually tried a number of items from their other food festivals, and most of the time I was pleasantly surprised. And the portions were generally good sized, not like DCA overpriced and tiny. So I'm looking forward to this!
It was often a pain to stand in the same food booths as other people ordering regular food, whose lines move abysmally as it is. So having dedicated booths should be a step up... I'm suspect the lines will still be slow, but now at least I don't have to wait for a family of five who are just getting burger combos.
