There are quite a few pub/bar around Da’an District and On Tap is one of them. They call themselves “Taipei’s Only Real Pub” and I could see why.. Comprehensive food menu, “on tap” beer, bottled beer, shots, spirits, makes this pub a nice place to hang around.. They also have daily specials, which is worth checking out.. Condiments for your food.. Monday’s Specials: Burger & Beer for TWD199, good deal I’d say.. Beef burger is nice, crispy bun and juicy patty.. On Tap: No.21, Alley 11, Lane 216, Zhongxiao East Rd, Da’an District, Taipei. 台北大安區忠孝東路四段216巷11弄21號.
