Romanesque Revival former Astor Library now hosting swank resto-lounge on the mezzanine. Earth-toned leather and pale wood space somewhat like a library, except one with a killer booze program. Reds, whites, champagnes, a half-dozen drafts, and clever cocktails like the absinthe-laced Bye Bye Albatross. Andrew Carmellini on the bites, with starters like calamari and chipotle, seasonal mains like trout, mussels, and short rib goulash. “Curtain Call” menu after midnight, perfect date-extender after an evening of theater. Although watch out for Professor Plum, candlesticks.
