I was in Cincinnati this past week for a work project and found this little juice bar about two blocks from my hotel. They serve up fresh juice fast and with a smile, and the prices were very affordable. Even when there was a line they got my juice to me in just a few minutes. Only downside is that they close at 4, so you have to get down there in the morning or during lunch break, but it's a great way to get out and get something nourishing instead of eating a donut or bagel.
Cons: They close at 4:00
