Horrible Food Experiences

I just had Chinese food for lunch. Typically, this would be a good thing. However, I decided to try something new this week: Hot Diced Chicken. It was spicy chicken cubes in some kind of ginger sauce with pieces of scallion in it. Sounds tasty.

Looks like someone threw up in a Chinese container and didn't feel like cleaning it up.

Also, tastes somewhere in between those two.

Not that I'm in the minority here, but I absolutely hate it when a food sounds really good on a menu, and ends up being shit. Are there any other foods like this I should watch out for? Because I don't want any more unpleasant surprises like this, whether I'm going out for Chinese, Italian, or whatever.
