Do what my sister used to do in the 70's when she didnt want to go on a date..... tell them that you're washing your hair that night.

Alternately, you could call at the last minute and say that you're sick, ill, not feeling well, feel like youre going to puke, ect.,ect.

Then again you could say that you've got car trouble, twisted your ankle and now its swollen up to the size of a basketball.

Or you could be honest and say that the food served there makes you want to puke, IF it doesnt ACTUALLY make you puke. No thanks not interested.

If you do end up having to go, eat before you leave home, order a Coke and nothing else when you get there.

Good luck.
