That mostly went away years ago, basically completely died in COVID, and the labor shortages in the service industry never eased up enough to maintain staffing at places that had late night hours. And I do mean not enough people; the housing shortage is so acute that service workers cannot find places to live.
You can trace all kinds of seemingly unrelated problems back to the "housing theory of everything".
I think the answer is they are a tighter knit community (potentially a family) than the average coffee shop, so easier to keep the shop staffed late.
Houston has addressed population growth by spreading ever more outwards, because it is flat with few natural barriers. Seattle hasn’t really had a choice other than to grow upwards, since it is hemmed in by lakes and mountains in every direction. But like most American metropolitan areas, most of the Seattle region has until fairly recently been opposed to density.
The resulting housing crunch has resulted in significant demands for wages to pay for housing. Houston follows the federal tipped minimum wage of $2.13/hr. Seattle does not have a different payscale for tipped workers so the minimum is $20.76/hr.
The rest of the country is even worse for night people like myself.
If I was a crazy billionaire, I'd open a good pizza place in SLU or somewhere central with pies that cost $20 for a large, open til 3 am. Maybe aim to lose no more than $5,000 per month. It would not be profitable with the crazy high minimum wage, so I would just accept the loss for providing this benefit to the city.
In cities like this people will travel a significant distance for hot food. And there’s always the delivery apps, too.
It was a lifesaver for me when I worked grave, I could go for a sumptuous dinner at 3 or 4 am.
I can't imagine a business closing over it, but having a closing time is a good way to get people to leave maybe?
Also, things have gotten worse after the pandemic. Low revenue after 9 pm (unless alcohol is involved), high labor costs, and safety issues means the juice is not worth the squeeze for most retail businesses here.
When I used to live in Chicago, the economics worked out differently, so there were many businesses that opened late.
Also, gloomy weather 7-8 months of the year makes you not want to socialize.
Revenue halted overnight, and often turned negative with breakins and general insecurity
