We discovered Cosi on our way from Layfette Square. We saw several Secret Service agents going in and coming out so we figured it must be good. We weren't disappointed. They offer a variety of delicious salads, sandwiches, soups, and even pizzas. The turkey bacon melt was sooo yummy and my husband and I also split a classic salad. My girls got pizzas, however, I think next time will skip the pizza and go for a sandwich.
This is a great place to stop.
