Playing with building blocks is not just for kids. For the last few years, The Brick Bar has been hosting traveling pop-ups (not affiliated with LEGO) in cities like New York, London, Sydney and Toronto, turning drinking beer and playing with the classic toys into adult fun. Boomtown Brewery, the brewery, taproom and events space in downtown’s Arts District, will feature sculptures made from more than a million building blocks resembling everything from a tennis table to a fountain to an adult ball pit. If you’re not too hammered, you can create your own sculpture in one of the building stations while downing a Bohemian Pilsner, Belgian White or any of the other craft beers. And no beer event would be complete without DJs and food trucks. Boomtown Brewery, 700 Jackson St., Los Angeles; Thurs.-Fri., Sept. 19-20, 5-9:30 p.m.; Sat.-Sun., Sept. 21-22, 11 a.m.-9:30 p.m.; $20.
