I see that there is an ad for the famous Keen’s Chop House, then in business for 53 years. I had dinner at the fine old pub style restaurant about 50 years ago, and it is still there. It is famous for mutton chops, and was originally a theatrical type place, from the time that NY’s theatre district was based in Herald Square, not Times Square.
Resteraunts come and go in the blink of an eye, but when somebody comes up with the right combination of factors - location, menu, kitchen talent, etc. - it can go on forever.
