Time stops when you pass through the doors of the Flatiron Room. Fifties-era Italian floral wallpaper, rolling library ladders, and a chandelier that once hung in the Smithsonian set the anachronistic mood; live jazz, performed on a velvet-curtained stage, seals ye olde deal. But what really takes a tippler back is the whiskey. Old, rare, indie, you name it — if it’s distilled from fermented grain, it’s probably here. There are nearly 1,000 bottles to choose from, including Gordon & MacPhail, the Maltman, and 27-year-old limited-run Glenmorangie Pride (sip slowly — it’s over $400 per dram). A private room upstairs offers tastings and classes. If you take a liking to a particular spirit, purchase a bottle and it’ll be tagged with your name and stored in a private locker.
