Addendum at Studio Bar is a hidden gem located in DC's Eighteenth Street Lounge in DuPont Circle. Cocktails at Addendum will be driven by the bitters, cordials, and aromatized wines we add to every drink. Base spirits will be just that: the basis upon which a cocktail's identity and personality is constructed. Citrus juices or syrups will not be used. Addendum's approach to cocktails is to apply a modifying agent such as vermouth or amaro to a base spirit of bourbon or gin in such a way as to reinterpret and reframe it, not merely to tame it. In this manner, what is added -- the addendum -- becomes the most important part of the whole.

Addendum is headed by Lukas B Smith and JD L. Quico.

Hours of Operation: Wed & Thur: 9pm - 2am; Fri & Sat: 9pm - 3am

It was during his graduate years in Athens that his love for food and drink developed into a professional interest. Since moving to D.C., Lukas has worked in many of the city’s creative and independent eating establsishments. He won the DC Craft Bartender's Guild Rickey in 2014, along with the USBG DC Bloody Mary Competition. Smith was named Bartender of the Year for 2015 by Eater DC.

JD L. Quioco has been in the hospitality industry for over 25 years. He graduated with a BA in anthropology and a minor in chemistry from the College of William & Mary in 1995.

As the GM at Dupont Circle's Dragonfly Sushi in 1997, JD realized this would be his profession of choice. He went on to be General Manager at Mantis Restaurant In Adams Morgan. In 2005, JD was asked to open and run Bar Pilar, and two years later took over the reigns at Bar Pilar's popular sister restaurant Cafe Saint-Ex. With the success of both establishments, JD was promoted to the position of Director of Operations in 2009.

In 2014, JD became General Manager of Biergarten Haus, the largest German beer garden in the district. He then went on to run Spike Mendelson's speakeasy The Shepard.
