Hehehe, the "Airbnb for food" tagline reminded me of the http://incubatorincubator.com:

Specifically:

"AirBnBForY. AirBnBforY specializes in incubating companies that are the "AirBnB" for their respective industries (e.g. "The AirBnB for pantry space" and "The AirBnB for condiments" (A lot of people aren't making full use of their mustard, ketchup, and other condiments. AirDiments creates a marketplace by which people can use each others condiments)."
