A loaf of bread, a jug of wine, and thou . . . well, you can get almost everything you need for an impromptu meal from the Mustard Seed Market & Café. Whether your tastes run to sushi or olive-orzo salad, peanut Thai chicken or grilled salmon, ginger-baked tofu or fruit crisp, you'll find it ready-to-eat (or heat-and-eat) at the Market Kitchen. Throw in a loaf of warm, crisp-crusted bread, a wedge of artisanal cheese, and a bottle of wine, and you're pretty much good to go. Except for the thou, of course; there, you're on your own.
