SandwichBoard does restaurant web sites (http://www.sandwichboard.com/).

We've found that the owners and managers who "don't get it" are the ones who think that the web site experience should be the same as the restaurant experience: background music, a menu that looks identical to the physical one, and a picture of every dish.

The ones who do "get it" entrust their web site to designers and usability experts who make it their goal to turn web site visitors into patrons.
