No,no,no, now here's what you do:
You go to a toy store or Spencer's Gifts in the mall or some place like that and you buy a plastic bug -- cockroaches work best, but any icky "bug" will do. It has to look (fairly) real.
Make a reservation at the restaurant. Show up, order a meal ...yup, yup, you're getting the idea... half way though slip the plastic bugs in/under some food on the plate (mashed potatoes work great for this).
Then wait a moment, leap up and cry: "Oh, my God!! There's a cockroach/bug in my food!!!"
Here you can add whatever dramatic touches you wish. But don't make it too long, or too obvious, and get out of there -- pronto!
The place will be in an uproar, and the restaurant's reputation will suddenly be....er...well you know.

Plastic bugs won't work, only the the real kind (dead, though) will do. :)
This reminds me of "Mouse Hunt". Remember when the restauranteur brother (Nathan Lane)lost all his business when the mayor died after eating half a huge cockroach?
Hey, just let loose a bag of bugs and watch the patrons scream....lol
