Our season of nontraditional pop-up bar inspiration continues: DC9 is opening a pop-up bar with a theme of … trash.

To remind patrons of the dangers of plastic things that pollute the ocean, the team is turning the first floor of the Shaw bar into The Garbage Bar(ge). The space will be decorated with plastic bags, six-pack holders, and the marine life that’s threatened by all our garbage, including dolphins and sea turtles. A portion of proceeds will go to the Chesapeake Bay Foundation.

The idea came to beverage manager Lauren McGrath when a customer did something “obnoxious,” like wave money at her across the bar to impatiently get her attention. “As all good bartenders do, I went into the kitchen and had a yell about it,” she says. “I said, ‘They can choke on their straw and save a sea turtle!’ Amber [Bursik, DC9’s kitchen manager] looked at me and said ‘That’s the pop-up bar theme.'”

It’s also timely: The pop-up is meant to celebrate DC9 ditching plastic straws. While the move comes as a response to the D.C. Council bill to re-up the city’s straw ban, McGrath, a vegan, says she’s “always thinking about ridiculous amount of trash we’re throwing away and not thinking about.”

Similarly, the beach-themed decor will be made from recycled materials. This is the place, remember, that turned its dim hideaway into a La Croix-studded temple to the vodka soda for its last pop-up, so expect full dedication to the theme. Or as McGrath puts it, lots of “straight-up garbage,” plus “when you go to prom and it’s ‘under the sea’-themed.” A former preschool teacher, McGrath is already dreaming up crafts made from plastic bottles gifted from neighboring bars, sea urchins made from plastic drink stirrers, and some sort of effigy (“that we won’t burn, because that would be bad”) made from the plastic straws they’ll soon say goodbye to.

The bar will develop a straw alternative for patrons with disabilities who use them. They’re experimenting with non-plastic options, McGrath says, and paper straws, with their “weird, papery, chemical-y taste,” are already out. For most, the bar will just quit distributing straws altogether. “We’re all going to have to get used to it,” McGrath says. “My lipstick will suffer, too.”

The team is promising a special menu of (shaken, not stirred?) cocktails for the space, which are still in the works. McGrath promises classic beach-themed drinks—sex on the beach, sea breeze—and she’s still tinkering with an oil spill-themed shot. Still, “I don’t want anybody coming in expecting super super fancy cocktails,” McGrath says. “It is DC9 after all.”

DC9 is located at 1940 9th St. NW. The Garbage Bar(ge) runs Dec. 17-30.
