I think they had some stuffed snail appetizer/entree that they put in
the shells. Hard to say for certain because I was always in the back
room and never ate there, but that would be my guess.

I always thought it was bizarre that they'd "recycle" something left
on a customer's plate, but I guess they viewed the shells as serving
dishes. The problem was that, oddly enough, the automatic dishwasher
wasn't made to wash the inside of snail shells.
