Decades DC can be hired for private events of 50 to 1,000 guests: corporate mixers, networking evenings, holiday parties, brand activations, college formals and birthday celebrations. The venue is a retro-themed nightclub at 1219 Connecticut Avenue NW in Washington, near Dupont Circle. It covers 15,000 square feet over six floors.
Seminars and company events
The venue is built for standing receptions, not for seated plenary sessions. Its official site lists corporate mixers, networking events, holiday parties and brand activations among the events it hosts, and says the layouts are flexible. Organizers can use one floor, several floors or the whole building. The site describes the space as configurable for exclusive private events from 50 to 1,000 people.
Professional DJs, a sound system and lighting come with the venue, and the team can program music and lighting for a given event. Branded signage and decor are offered as options. Promoter-hosted and ticketed events are also accepted, with production support and staffing from the venue.
Weddings and receptions
Decades does not sell weddings as a service. It does host engagement parties and celebrations, with curated music, bar options, personalized LED signs and presenters. For parties booked well in advance, the team can decorate the floor or VIP tables with balloons and arrange a cake.
Rooms and capacities
The building has six themed floors, each tied to a musical era, and eight bars. Named floors on the site include a 2000s floor, a 2010s floor and a hip-hop floor. The rooftop has a retractable roof that can be fully open or fully enclosed, which makes it usable for day parties and happy hours in spring and summer. VIP sections and reserved private areas can be added to an event.
Catering
The site mentions food and beverage options for groups aged 18 and over, custom cocktails for guests aged 21 and over, and bottle service packages. It does not describe a seated catering offer, so organizers should confirm the format they need.
History and setting
Decades is run by Antonis Karagounis, who has worked in Washington nightlife since 1994. The club draws on club culture and music from the 1980s to today. It shares ownership with sister venues named on its site, including Zebbie's Garden, Ultrabar DC and Wilson Hardware.
Getting there
The address is 1219 Connecticut Avenue NW, Washington, DC 20036, near Dupont Circle. The site describes access from downtown, Adams Morgan, U Street and Georgetown. Guests under 21 can attend certain events, so check age rules when you book a student or mixed-age group.
