I once ate half of an enchilada entrée, then found a nail which was baked into the enchilada. Not a hardware store nail, a HUMAN nail!! I called over the server and she offered to bring me a new entrée. That was the last thing I would have wanted! I should have complained and got the meal for free, but I was young, not very assertive, and felt that I needed to leave that place ASAP. I felt like throwing up, but didn't.

What have you found in your restaurant food?
