Yeah, Cosi is retarded. There's one a block away from my office but I'm more likely to walk the 3/4 mile to the Panera.
You were also a bit retarded, though, for ordering a drink from one of those places. Unless you're at a McD's with a dollar menu drink, you're gonna get charged like $2 for a regular size drink.
I do the pick two from Panera, sometimes picking a salad for one part but sometimes the soup. For the other part I take a sandwich. The sandwiches are good. This will run about $7.50 these days though. I feel like it used to be cheaper.
