David Zebny's non-chain chain Z Square
David Zebny, the man behind Z Square, may have discovered an underserved niche between the bakery-cafes (read: Panera) and the casual dinnerhouses (Applebee’s, et al).
Some operators are looking to source lesser known but abundant seafood that often turns up in the by-catch. These “trash” fish may have names that could sound off-putting to consumers, such as lionfish, sheepshead or grunt, but innovative chefs are proving that their flavor and texture stand up to their upscale cousins—at a gentler price. And diners are biting.
