A poor student here has offered something similar: you pay for the food, he'll come cook for you, if he can join you for dinner. He got thousands of requests (see http://politiken.dk/indland/ECE1778538/halvfattig-tilbyder-a... )

Someone has taken the idea and try to scale it since: http://www.facebook.com/cook4food

It's social, it's local, it's mobile, it's cooking!
