I love Cosi and go there often when I'm in Reston - the flatbread is delicious and consistently fresh. The soups and salad are also very good. There is a lot of indoor seating and a limited amount of outdoor seating. I wish that we had a Cosi in Loudoun County/Ashburn!!! My favorite sandwiches are Buffalo Blue, Chicken Tomatoe/Basil/Mozzarella (TBM), and I love the tortilla soup!
