Although I completely agree with you, and I'm sure most HN-type people would. I doubt the restaurant owners would. The idea that a website has to be flashy and fancy is well ingrained by now.
See I think that statement is a fallacy. Restaurant owners began to believe in the power of websites when other restaurants began having them and HN-type people began using them, and they saw what a great tool the internet is to draw more business and promote themselves. HN-type people (love this hyphen) create the groundswell by which businesses recognize what direction to go in, and restaurant owners are no different, just a little later to the party because they've been cooking the meals.
