Mojo is a nice treat in the spring or summer and a good excuse to take a stroll on the sidewalks of CityNorth.
However, the teenagers that work there are not very customer service oriented, the yogurt is just satisfactory, and the serve-yourself-and-weight-it-later concept can come with a scary price tag.
That being said, it's still an good alternative to Cold Stone, and the decor is very "Clockwork Orange."
FYI - ask for sample cups so you can test the yogurt. They no longer keep them out because kids were coming in and filling up on samples and then bailing.
