For me at least, I found it was a lot more common for myself and CP's to be scheduled at character dining locations in the parks. My home park is Epcot, and I did get the chance to work at the Garden Grill and Akershus in Norway during my CP. I also had friends who worked a bunch of times in character dining locations at other parks, such as Crystal Palace in MK or Hollywood and Vine in DHS. It is still much less common to be scheduled at those locations, since there are way fewer attendants in a restaurant than there are at other park locations, but it can definitely happen! Like progroupie said, you well get a feel of where you'll typically be scheduled. I was "bid" at one location in Epcot for literally more than four months during my CP, but others had schedules where they would typically be at one location on Monday, and somewhere else on Tuesday...
