I have found another way to resolve this by going into your windows services and restarting the "Windows SharePoint Services Timer". Doing this will fix the problem and get your menu back without having to do an iisrest. Also your users won't see any "service unavailable" messages when browsing sites or have any after effects from doing it.

After you reopen your IIS Manager you will now see the little '+' sign so you will now be able to expand your menus. I know its not a big fix but maybe it might help someone... somewhere. ya gotta start somewhere right?
