I don't know if there is a link, but AllEars.net lists the Disney menus and usually has the opening hours of the resort restaurants.
Park restaurants vary in their operating hours as park hours vary, but the generaly tendance is from some time at or after park opening to 15 minutes before official park closing on any given day. Some places open for breakfast before the parks officially open but I think it is mostly/only character meal locations so you would need to check this first. If park schedules are out for the dates you are planning on visiting and that should give you an indication.
