Slate asks. Why are restaurant websites so horrifically bad?

While lots of people have noted the general terribleness of restaurant sites, I haven't ever seen an explanation for why this industry's online presence is so singularly bruising. The rest of the Web long ago did away with auto-playing music, Flash buttons and menus, and elaborate intro pages, but restaurant sites seem stuck in 1999. The problem is getting worse in the age of the mobile Web--Flash doesn't work on Apple's devices, and while some of these sites do load on non-Apple smartphones, they take forever to do so, and their finicky navigation makes them impossible to use.

I've also pondered this for years.
