St. Petersburg Distillery now has a reason to stay after hours.

The local distillery, located at 800 31st Street South, recently debuted 31 South, a hidden second-floor Prohibition-style lounge that’s now open Thursday through Saturday evenings from 6 to 11 p.m.

“During the day, St. Petersburg Distillery is a place where guests can experience the spirit of St. Pete in our Spirits Garden, Welcome Salon, and tour Florida’s top craft distillery,” said Evan Brownstein, CEO of St. Petersburg Distillery, in a statement.

Now, at night, guests can discover a whole new experience, a place true to St. Petersburg’s elegant bootlegger spirit in a convivial club-like social setting.”

Cocktails are the focus, and will be made from the distillery’s own handcrafted spirits. A few of the drinks up for grabs include a Maple Old Fashioned with Old St. Pete Sunshine Whiskey, and a specialty Espresso Martini, Matcha Latte Martini with Banyan Reserve Vodka, and more, says the press release.

On the dining side, the 45-seat venue tapped Chef Johnathan Rodriguez, who was previously at Sal Y Mar in Midtown and was on the Food Network show “Supermarket Stakeout.”
