I got the message that you were offering to create mobile sites for restaurants, but maybe it's because I'm already used to the idea. I think you may be overestimating how many people have and understand smartphones, though. According to slide 62 of the Morgan Stanley “The Mobile Internet Report Setup” you link on the front page, there's only a 25% percent penetration (est 40% by the end of the year). After a quick skim through the presentation, I don't see your 42% anywhere, but perhaps I don't know what I'm looking for.
Anyways, the point is that you're not marketing to the smartphone users. You're marketing to people that probably don't have a smartphone, and may not know how people would use one to discover their site. Showing the different paths in a video or chart would be a good idea. Better might be to set something up with an existing customer with a horrible, flash-filled, pdf-menu'd main site. Get them to agree to let you post a video of what it was like before they got you, and how unusable the site is, even if you somehow get a direct link to the pdf menu.
