Didnt they once have a set up near the escalators once for some kind of service? I mean the Lerners are Jewish.
You may be thinking of the Os.
Seriously, the Os I think had the first kosher stand behind home plate at OPACY and used to have a room for the nightly Minyan near there. Useful if you are in the 11 month mourning period when you are supposed to say the memorial prayer twice a day in a group of at least 10 (traditionally, men, but many places are "egalitarian").
