The yogurt has pretty good reviews, but doesn't get as much attention as some of the business' other attractions.
The stores are known for a nightclub atmosphere, with pounding techno music...
...And its, uh, largely female staff.
Also, like Hooters, the name CUPS doesn't appear to be an accidental double entendre.
The business is growing quickly and doing quite well, so don't be surprised to see one in your neighborhood sometime soon.
