Last seating time for restaurants in the parks?

[Danauk]

How long before the parks close can you make a reservation at a table service restaurant? We want to eat at Walts and was origionally going to make lunch reservations but I would prefer dinner there. The park closes at 8pm during our trip so when would the last seating be for dinner?
Thanks

It would be 7pm, one hour before park closing time.
