Cosi is a little sandwich and salad place, perfect for a quick lunch or dinner. The atmosphere is cold, with concrete floors and uninsulated ceilings, kind of industrial unfinished, but the food is left of ordinary. The roast beef and wasabi sandwich is interesting, the roasted/grilled veggie sandwich is better than the usual offering. They make salads and sandwiches to order, and the s'mores with a mini-hibachi for roasting marshmallows are a hoot for dessert. They aren't terribly interested in having child guests, but we've done a birthday there just for the s'mores. This is a good compromise place when you don't want fast food, but don't have the time for a regular restaurant.
