This is the most important piece of information that is missing from your site. As a restraint owner looking at your site I'm thinking "What is this, an app, or a service or what?" and "how will my customers find my restaurant on their phone with this service?". Given that most restaurants that you are targeting are probably not even aware that people might access access the restaurant's site on their phone, you definitely need to answer these questions.
(edit: for example, your uWink demo video in the first frame already starts with the app (or site or whatever it is) on the screen. You should demonstrate how a customer would find uWink on their phone in the first place)
