are you under the impression he eats at a restaurant and then checks reviews to see if it was good?

I don't find reviews helpful in making a decision for a restaurant - as long as the food isn't so bad it'll make me sick it's fine. I do like to see the menus and opening hours, though.

But a lot of people really do appreciate that kind of help, so much so I don't think any competitor will get anywhere without that kind of data.
