Because District is situated inside the new downtown Sheraton, it's expected that hotel guests would eat here. But interestingly enough, the restaurant seems to be going after locals, too, with a comfort-food menu that name-drops plenty of local purveyors and gives creative twists to American standards. One such classic is something we just don't see on restaurant menus in the Southwest but wouldn't mind if we did: whoopie pies. These traditional Amish treats, with cream sandwiched between two moist round cakes, get a tasty update at District. They're pumpkin instead of the typical chocolate cake, teamed with a frothy bourbon malt milkshake that's as yummy as it sounds. Earlier this year, the New York Times published a story about how whoopie pies are suddenly in vogue. We knew it already.
