That 10% seems rather unlikely. Are you sure that isn't just of restaurants that take online bookings, not of restaurants that take bookings? In much of the world, the vast majority of restaurants that will take reservations do so via telephone, and OpenTable has 0% of that very large market, which would make it pretty much impossible for their overall market share to hit 10%. Even in much of Europe: for example, nearly every tavern in Greece (tens of thousands of them) will reserve tables via telephone, but very few of them have any kind of online presence.
