We are always striving for the best, the best hotels, the best food, the best wine etc.
How about a contest for the worst (really existing) food ?
There used to be an institution called "The not so terribly good club of great britain" and to be a member you had to demonstrate that you were exeptionally bad at something. They sometimes invited members to demonstrate their inabilities on stage. They soon had to close down because according to their own statues they were too successful.
But we could make a list of the worst food, starting with a dish that let you vomit by the pure looks of it up to last place where you needed hospital care (Psychologist or Gastroenterologist) after yoyu had the pleasure to taste it.
Cheeze wiz on wine is a strong contender in this list I suppose. And the breakfast beans etc......
