A Question : There is a some local Turkish website called yemeksepeti.com ( = food basket/cart. They have english version of their web site if you want to check ) which in service since 2001. One can see the menu and order any meal from the member resaturans and get his food in 10 to 40 minutes without paying extra fee.

If one implements the same system, he can kill the middle man. What prevents other start-ups to do that and how can zerocater protect it's business ?
