Located near the intersection of Mabashi street and Waseda street in Koenji is craft beer shop Drink Up, stocked with a good range of local and Western beers. However, don't expect any of these beers to be available on tap here. All of them come in cans, which you can pick out from the refrigerator.
The selection changes roughly every two weeks, but you'll always find a good mix of about a dozen beers including classic IPAs, blonde ales and pilsners as well as more unusual flavoured brews like apple pie, guava and lime, and white chocolate.
