When we were there last week for pm EMH, I know the counter service was open later than 5. I specifically remember this because we raced through the park to get to the jungle trek before it closed at 5 (barely made it!) and we ate after we were done (probably around 5:30 or so). I think I also saw people in the table service restaurant at that time, too, but I have no idea if they had ADRs for before or after park close to the public.
