MODERN LOUNGE CULTURE. Five international DJ's spin your favorite funk, house and lounge tunes, Thursday, Friday and Saturday from 10pm on. Our sexy knowledgeable staff can serve up a classy cocktail from our extensive list that will impress any connoisseur. And unlike Dutch "no can do" tradition, if its not on the menu, we'll make it! Enjoy a great view of the Leidseplein from the upstairs lounge. Boom Bar, day and night. Relax and let us serve you! Boom Bar serves a great lunch menu every day of the week from 11am-4pm with healthy sandwiches soups and salads. A new exciting dinner menu is served from 6-9:30pm, then we switch to lounge mode. Join us on Sunday and chill the day away with easy listening tunes and a great Brunch menu. Add fresh juices or a Bloody Mary and you have the perfect way to spend a Sunday.
