I recently visited this Cosi on a weekday about 2pm. I was thrilled to see how many tables were open -- this may seem late for lunch, but it was rough finding a seat in the neighborhood at the time.
I am a BIG fan of Cosi bread (especially when it is hot and just a little bit salty). I enjoyed my cobb salad, but was disappointed in spending over $10 for a salad & a drink. That's Manhattan business districts for you.
