I have found a few restaurants that will donate a % of the proceeds from an evening, all you need to do in advertise and have people eat there!

Chick-fil-a

On the Boarder

Claim Jumper

Joe's Crab Shack

Arby's http://www.arbysrestaurant.com/inpage/our-community.cfm

If you know of any add to the list!

This is an easy way to raise awareness and $!
