I think Bauer's right that many trends start at the top. But—duh—just like fashion, just as many (more?) start at the bottom, a.k.a. the "street." Owing in large part to the recession, we are in the middle of an exciting era of cheap food. Ice cream shops, street carts, sandwiches, pizza, hot dogs, beer rather than wine—these are the foods and drink people are spending their dollars on and getting excited about right now. Innovation is happening just as fast in these arenas as in $100 a plate, reservations-only spots. And fancy places now borrow liberally from the formerly-seen-as-lowbrow: Deviled eggs, boiled peanuts, doughnuts, and beef jerky have all had their day recently on the menus of expensive restaurants. In fact, more and more these days, it seems the only things that separate fancy from casual are portion size and price tag.
