I believe that from 6:00 to 7:00 everything closes except sit down restaurants to empty out the park but before the park closes and after the park re-opens there are a few counter service places open like Main Street Bakery, Plaza Ice Cream Parlor , Casey's Corner, Pecos Bill Cafe ,Westward Ho Refreshments, Scuttle's Landing, Pinocchio Village Haus
and Cosmic Ray's Starlight Cafe. I got these from last year's party park map.
