Walking into the old Kitty O’Shea’s space on State Street is something of a different experience now.

In its place: Bostonia Public House, a bi-floored, 1920s-style post-work drinkery rife with coffee tones and vintage-ness, designed by HGTV Host and Designer Taniya Nayak. Slipping into a leather throne with a date at the 52-seat walnut bar (tip: grab the bar love-seat against the padded leather lean rail modeled after the Refinery Hotel’s version in NYC) will mean facing some rare scotches on a custom display wall that bar manager (and Abe and Louie’s veteran) Joe Corrado sees as apt given the rarity of the spirits.

“You don’t see many around town of this type,” he says of their vintage 1958 and 1965 Glen Grant bottles. And rejoice, they’re next in line to procure some Pappy Van Winkle (slow clap).

The old scotches, antique marble, and booths mimicking the look of a suit (seriously) flank an impressive 45-bottle strong Napa Technologies Wine System near the “mayor’s wall”, featuring official portraits of every Hub overlord since Edwin Upton Curtis in 1895 (who later incited the Boston Police Riot of 1919 as Police Commissioner).

You’ll be facing a classic cocktail list of old favorites, some with a twist like the J. Grady; a modified Old Fashioned using Luxardo maraschino cherries, blood orange (“gives it a different citrus”), brown sugar cubes instead of white, orange bitters, and Angel’s Envy Rye Whiskey that’s finished in Franco Caribbean Rum casks formerly housing French cognac (spirit-nerd-to-English translation: it’s good).

There’s fitting piano-driven live ragtime and crooner music every night to partner with theBoardwalk Empire vibe, as well as their dangerous, silky-sweet Diva (Nantucket’s Triple 8 Vanilla vodka, Disaronno, pineapple juice with a prosecco float). And it’s already a hit.

“There will be babies made because of this one,” Corrado jokes. “Fact.”
