While offering an impressive menu and selection of alcohol Tree bar is known for two things: beer and pizaa. The Belgian owner has brought a bit of his country by offering a variety of Belgian brews as well as a selction of other imports. The pizza is made fresh in wood ovens that are the center piece of the restaurant. The bar is littered with various bottle openers that have been collected over the years. A great place to begin an evening out in the Sanlitun area. The frequenters of the bar are white collars working in nearby areas, foreign travelers and art lovers.
