cosi at chestnut/4th is a little rundown inside, but you can get cheap eats and a carmel mocha latte at the tables outside across from a national historical park, next to a 4star hotel, in an international style building also housing Mary's and Buddakan, with few annoyances in the early am. it has a certain uber-unhippness to it that makes it A-OK if you can just pretend to forget that it is a chain.
