In ShortIf you don't mind sacrificing elbow room, the tiny 700 Express--tucked tightly into a corner behind Marketplace in the downtown Minneapolis Marshall Field's--offers an elegant upgrade from fast food. Salads and pastas dominate the menu, but soups, sandwiches and daily specials are also offered. There's the rich strawberry champagne chicken salad and the chicken Czarina pasta in a Parmesan white sauce. Desserts change daily, but items like the fat-free cheesecake are usually worth a peek.
