I haven't, but I also don't like CCC. I went to Maggie Moos, the place they imitated and placed in malls around the US so I have a bias against them :)

The fact that many stores used to have the young employees do "ice-cream raps" didn't help me any, but just looking today their fake fluorescent colors in ice cream just don't look like my thing.

Maggie Moos is easy for me to get too though - down in Shirlington.
