The page loaded for me so I deleted the Adobe Flash plugin and reloaded. The page detected that I wasn't running Flash and asked me to click a link to install it. The page once again loaded properly after the reinstall.
Does the Pizza page briefly appear for you before the entire page goes blank? If yes, odds are pretty good it's an issue with Flash.
1. Check to see that you're running the latest version of Adobe Flash (Current revision 10.1.85.3).
2. If you are already up-to-date, delete and reinstall Flash.
Hope one of those works!
