It’s no surprise that Barcade has expanded to six locations in four cities since it first opened in Williamsburg in 2004. It has a simple and foolproof recipe: Take an unassuming bar with craft beer and decent music and add dozens of classic video games. Barcade satisfies because of what it avoids: no swipe-cards, no expensive newfangled games, no kids. You get just the arcade classics of your youth — Ms. Pac-Man, Galaga, Q*Bert, Tetris, Arkanoid, Dig Dug, and Centipede — all for only a quarter. Of the three locations in New York, the original Barcade in Brooklyn has the best selection. But Barcade on West 24th does have Golden Axe and a rare and beautiful Discs of Tron from 1983.
