We were sitting in a studio, an odd mix of people who included another now good friend, Myrtle Allen of Ballymaloe House in Ireland. She is a restaurateuse of great distinction, suitably garlanded by Michelin, and she had just opened an eating house in Paris.

It's not a spin-off, since none of the characters are the same. (the fact that the actress is the same doesn't make it a spin-off--in Cheers she played a cheery British barmaid and in C.A. she was a crusty American restaurateuse.) However, it is an example of a rip-off sitcom (using the same basic premise that has succeeded elsewhere).
