Because the Roaring Twenties were apparently not just an early Cretaceous decade dominated by enormous, plain-roaming Mega-Lions, hit the Gatsby-esque William Jeffrey's Tavern. Now open from the crew behind Rhodeside and Ragtime, it's built out with '20s-reminiscent elements like iron-cast/ patina fireplaces, barnwood slate tables underneath streetlight fixtures, and three Edward Hopper-y murals of speakeasies, including Rosslyn's own "Knoxville's Sunday Bar", from which Jackasses could be seen stumbling out night after night.
Tavern specialties include entrees like pan-fried flounder w/ sauteed Swiss chard & truffle gribiche, an Argentinian 10oz hanger steak w/ chimichurri and shoestring fries, and sliced egg white w/ deviled egg mayo, smeared between Texas toast and called the "Deviled BLT", also what Satan serves to his tormented souls...hellishly not cut into triangles! The 'tails mostly put new spins on classics, like the rye/ brandy/ sweet vermouth/ bitters French Quarter Sangria, a chocolate Old Fashioned, and the blackberry/ honey/ Absinthe/ grapefruit/ brandy Swizzle, presumably first enjoyed by Stoop Dogg, an early 20thC newsie who sat outside and played stick ball and stuff.
For those looking for something a little sudsier, they've also got 16 drafts (Victory Donnybrook, Joe's Premium Pilsner, Boont Amber...), and a load of bottles and cans, even though the only hops around in the actual Roaring Twenties were possessed by the magnificent Kangaroostadon.
