"Oh no... I did NOT just bite into that..."
What are your worst food experiences?
Mine was when I took a friend out for a sushi dinner at Ennju's - we ordered a large portion (around 36 pieces) of assorted sushi and on the final sushi, which was offered to me by my friend, I bit into a piece of glass.
Luckily, it didn't break in my mouth but the possible consequence has never made me go back and to bite softly (or crush with your tongue delicately) on the piece of food you are about to embrace.
Try recall THAT taste, experience, situation and share your tales!
