> Most people either never make restaurant reservations, or do so infrequently for special occasions, in which case they probably already know where they want to go and how to book it.

And even if they don't know, they likely either live in a small place, in which case there's not going to be a huge amount of choice, or a big place, in which case there will be actual guides written by people whose actual job it is to review restaurants. It really seems like a solution in desperate need of a problem.
