I avoid buffets at all costs. way to much left out and recycled food!
As a firefighter, I've had many late night and after hours fire calls to restaurants and local eateries. After seeing various kitchens and related things, the way that food is stored (or not stored). It significantly cut down on the number of restaurants I will eat at.
We have three big buffet places in town. And I could tell you, they are the landfills of eateries. The funniest thing is, the most "exclusive, classy" restaurant in town, had the filthiest most disgusting kitchen and walk in freezers I have ever seen.
