Casual cafe and deli chain offers a health- and eco-conscious alternative to traditional fast-food fare.. In Short Called "O to Go," by its growing circle of devotees, this Seattle-based chain specializes in seasonal, quick-casual fare prepared without chemical additives. Patrons--ranging from college students to corporate types--fill up on snacks and meals in the cafe or purchase prepackaged entrees to go. Breakfast-menu highlights are yogurt-fruit parfaits and sun-dried tomato-and-egg burritos. Lunch and dinner options include basil-chicken chili, meat loaf sandwiches and grilled salmon wraps. Also available are soups, salads, muffins and desserts.
