When I was in Seattle there is this pizza place in a suburban neighborhood that only open for 3 hours 4 days a week from 2:00 to 5:00. All of the workers were the same ones every day and they all three looked no nonsense but friendly enough when you ordered .
The pizza was really good and the calzones were fantastic, so I would go there often, but I almost never saw another customer in the place even though they had at least twenty tables with four chairs at each table set up in two giant dining rooms.
And they were in and out of the way spot with a very small sign. And I think at the most I ever saw one table taken up when I went there and that was only once.
And I never waited in line.
It just seemed like a really odd disposition for a pizza place that obviously needed to pay for a pretty high overhead considering how much space it took up.
