Located near the entrance to the Toyoko line tracks in Yokohama Station, this is a convenient spot to grab a pint or a tasting flight when you're passing through the area. It's part of the food court area on the B2 level of Cial Yokohama, so you have a wide choice of snacks to go with your beer - the two closest food stands specialize in Chinese dumplings and Brazilian churrasco-style grilled meats.
Eight taps dispense craft beers in various styles, including one original (Tap9 Brut IPA). A recent taplist included brews from Carlow Brewing (Ireland), Kyoto Brewing, Fujizakura Kogen (Yamanashi) and Coedo (Saitama). Beers come in three sizes, and are mostly priced at Y770 and Y1,400 for half-pints and pints. Three-part tasting flights are Y1,210, or you can assemble a four- or five-part flight since all the beers are available in 120ml taster sizes.
Sit at any of the tables in the food court area, and order food if you like or just beer. Just remember to return your glasses to the bar when you're done. Note that Tap 9 is just downstairs from 800 Degrees Craft Brew Stand (in the NeWoman complex) if you want to do some bar-hopping without leaving the building.
