I've been to many quickly's, but this seems to be 2nd to the most questionable boba's I have tasted. I mean it tastes good, but there is a taste in the boba that I'm not quite comfortable with. No it isn't that watered down but it is quite...."flavorful". I'm guessing they don't clean their tools to scoop boba or the drink into the cup or whatever.
A good alternative is may restaurant which is almost next door.
