Comparatively speaking, Boba Tea House is probably one of the top 5 boba places in Arizona.  With that in mind, I must say their consistency is spot on.  I have been a repeating customer since they opened in the mid-00's, and the quality and service has been the same since day one.  My only critique would be they should have never abandoned the punch card program.  Most, if not all coffee shop I have visited has one, so why not Boba Tea House?
