I've been here a couple times and although the bubble tea is pretty interesting, it's not quite memorable but does make you want to go back for more. The matcha tea I had one time tasted like fish (a sign that it has gone bad according to Google). None of the bubble teas are too sweet, they're actually quite the opposite, the sweetness is faint so you really taste the quality of the tea.
Shame they're closed right now and was replaced by yet another bubble tea place.
