Cosi Coffee and Bar is located in Bryn Mawr. It serves food, coffee drinks, alcohol and desserts. The menu of food is fairly small, but there are some good choices. The drink menu is large- there are hot drinks (coffee, tea, cider, hot chocolate, etc..), iced drinks and some with and some without alcohol. All are great. But the fun thing at Cosi is ordering Smores. They bring out a little fire with marshmallows, chocolate and graham crackers. You will have a blast toasting marshmallows. They also serve a twist on the Smores, called S'mmm…Oreo. Instead of graham crackers you get large Oreo cookies wafers. Yum!
