I have a couple issues with buffet service. You have everyone in the restaurant touching the serving utensils...even the people who don't wash their hands after using the restroom. When I go to places like Golden Corral, the number of morbidly obese people among the patrons speaks volumes. They eat volumes too. Why not? They intend to get their "money's worth" out of that "all you can eat" buffet.
I patronize a couple good restaurants in town. I know many of the cooks and I'm aware of what is going in the food . Otherwise, cooking at home is the safest bet.
