Just to add, when I worked at Cindy’s, our last ADR during the summer was at 9:35 (I think? Maybe 9:45) and our “walk time” was 11:10 (or 11:20, I might be going crazy to forget these, but it was back when they had walk time, so back in the day) as a “seater” (host). So it’s true that the restaurants staff for time after, and we normally had people out of the restaurant by 11 or 11:15, but sometimes is was much later. We started out closing sidework as soon as the last guest was seated, and we were normally busy until we left. But I might like to offer a different idea, most restaurants are designed to be pleasing when they have people in them. If I was the last family in any restaurant, it would feel weird and I wouldn’t be feeling at ease or relaxed, especially when I was seeing other people doing their cleanup work, even if it was on the other side of the restaurant. I think I would probably think about how empty it was at Cindy’s if there were less than 5 tables there. It would be noticeable, even if you were one of the oblivious taking their time families.
But at a qs restaurant, there is a difference between sticking around and taking 30 min to eat after you order and an hour plus.
I agree about twilight!
I would go with the ride strategy, that way you can meander out and not stop any particular place from closing normally.
