After spending the morning protesting up on the square, my friends and I trooped down State street looking for food so we could continue protesting.  Cosi was a good place for us to land up.  The food was hot and very tasty.  I had a small cup of the spinach and artichoke soup which was creamed - honestly, it would have been better if it was not creamed.  I also had an Italian sandwich that was great.  My bill was about $10.  They delivered the food to our table.  The music in the restaurant wasn't loud and the servers were friendly.  As a casual dining chain restaurant, it's pretty good with better than average fair.  I will definitely go to this and other cosi's again.  For a quick bite (though we weren't rushed to leave), it's a good restaurant to go to.
