It seems like a fantastical idea: open a bar that revolves around more than 70 painstakingly recreated 19th-century cocktails. Yet the Dead Rabbit Grocery and Grog, the vision of Irish bartender Sean Muldoon, is a bona fide hit, set in an old Financial District townhouse redolent of New York's bloodthirsty gang era. The Taproom is where the Wall Street boys go for Pilsner Urquells and the best Rum & Cokes they've ever sipped (here it's a Cuba Libre with Saint James Royal Ambre Martinique Rhum, lime essence and the Mexican, real-sugar version of the cola). Upstairs is where the cocktail adventurers ooh and ahh flipping through too-pretty books of vintage drinks-cobblers, flips, and juleps among them-that embrace captivating ingredients like eucalyptus tincture and clementine juice. A must-have round of Scotch eggs is yet another blessing in this food-deprived 'hood.
