If you are looking for the F! package, you won't have a lot of choices - there won't be any past 5-5:30 PM. Most of the F! package times are between 3-5 PM, although I think they were doing lunch times recently as well.
For a regular dinner w/o the package, it's still going to have to be early. Allowing 90 minutes for dinner, and lining up 45 minutes-1 hour before the show (minimum most times of the year), you would still have to schedule dining by 6 PM for a comfortable margin.
