When the room isn’t transformed into Feinstein’s at the Loews Regency for famed crooner Michael Feinstein’s cabaret act (among others), the Regency Hotel’s in-house restaurant, 540 Park, is the site of power breakfasts. The dining space seats 100 or holds 150 for cocktails. The less formal library has shelves of books, comfortable couches, and checkerboards carved into tabletops.
