I can't argue with stale format other than to say that if you're visiting restaurant websites wanting a unique browsing experience then I expect you're in an extreme minority. Would you happen to also be opposed to bootstrap?

As for poor information, I don't see how that's the result of Facebook. Plenty of restaurants neglect all sorts of information on their websites. Add in that plenty didn't bother with websites before, but now have a Facebook page, I'd say Facebook has drastically increased the amount of information available on restaurants.
