GB Brewery Restaurant – Taipei DunBei Store is a pub-style restaurant next to IKEA in Taipei that serves house-brewed beer, American food, pizza and pasta. Its signature items are beer brewed on site, cheeseburgers and chicken carbonara. A sampler lets you taste five or six beers in small pours, and the place gets busy enough to queue on Friday evenings. The food is more ordinary than the beer.
