Has anyone tried this? I just saw a newspaper article about it and I know I've seen other groups do it. Post in the comments if you've had success with this sort of endeavor, and add your thoughts to the fundraising ideas wiki too.
From the Napa Valley Register:
Dine & Donate is a wonderful way to give up cooking for one night, benefit Mary's and one of Napa's Fantastico parks all at the same time! Mary's donates 20 percent of all proceeds.
