I've used this app several times and each time I found an exceptional bottle that I would not have known about. I highly recommend it for restaurant owners for their guests. I know I up-sold myself each time I dined at a spot with this app. If I owned restaurants I would definitely have this. It so easy to use.
Something like this [Uptown Network] is going to be what separates the competitors, and what it's going to give you as a restaurateur is the opportunity to generate more revenue, generate more excitement at a nominal cost.
