Delmonico's, the restaurant where Frank was shot, is an actual New York City establishment. The interior looks interesting, with large panel paintings of restaurant patrons covering most of the walls. I tried to find out who painted them. It looks like the artist is an anonymous painter.

Below are shots of Delmonico's lush interior and walls decorated with panel paintings.







The building has a complicated history: it has been demolished, relocated, rebuilt, and several Delmonico's built around New York. The final incarnation which we see in Blue Bloods is back on Beaver Street.
