The Deichtorhallen is a turn-of-the-20th-century gem, two adjoining steel-and-glass structures near the harbor that once served as market halls and these days house temporary art and photography exhibitions. Tucked into a wing of the vast spaces is an intimate, minimalist dining room where chefs in an open kitchen do nouvelle takes on German standards that are works of art in themselves, along the lines of pink-roasted breast of goose with saffron-flavored rice and pan-fried zanderfish with bacon-studded Sauerkraut. Coffee, pastries, and light fare are available in the adjoining cafe throughout the day, and any daytime visit should coincide with a walk through the galleries, open Tuesday through Sunday from 9 to 6 (admission is 9€).
