dinner theater, n.All

Dinner theater is a way of positively guaranteeing that both food and theater will be amateur and mediocre, which means unthreatening and therefore desirable.

A Dinner theater is an establishment that cleverly escapes judgment on the quality of its food by distracting its patrons with a lively show, and likewise eludes criticism of its entertainment by keeping the jaws of the audience continuously occupied with more substantial fare.
