Sea Ranch in Wilmette is an interesting combination of a fresh sushi restaurant and frozen fish market. The sushi chefs at Sea Ranch work hard all day crafting California Deluxe, Spicy Caterpillar and Crazy Chicago rolls. While you're waiting for your sushi, you can shop for frozen Tilapia or potstickers. The seating area at Sea Ranch is small, so you may prefer to eat your lunch back at the office.
