I think the five stars reviews must people from people who have never had boba elsewhere before, and have conflated the lovely drink with this particular establishment in their reviews.
The boba itself is usually fairly good here, at least most of the time, but this it's not very welcoming. The staff is either friendly or uncaring/weird, depending on who you are - and if you're not friends with them from elsewhere it'll almost certainly be the latter. Service is rather bad, you're likely to be mischarged (check your receipt!), given the wrong thing, or you'll end up waiting forever for your drink.
Most of the magazines are Asian, so unless you read then you won't enjoy those, and the games are frequently missing pieces. The computers are almost always occupied and if you go in the evening you're likely to run into annoyingly loud groups of kids.
Go a mile west and get a sandwich + boba at Lee's or just get boba at Boba House.
And to the dude who is impressed by all of the "real live Asian people", seriously? Do you also judge mexican food places by how many mexicans are eating there? Or maybe you were just unaware that "real Asians" existed in Arizona? Stop being (or at least sounding) so ignorant.
