I've tried doing online ordering from a local restaurant a few times over the past week or so, and as soon as you go to the 'online ordering' page it just pops up a 'loading' spinner that sits there forever. I figured that the site was just broken, and it turns out that it is, in a way.
After finding that it's working for other people I hooked up a debugger. It turns out that it won't load if you have Facebook blocked. Why on earth does ordering from a restaurant require Facebook?!
