This place is closed for good now. Drove by and the shop is torn down. Turns out the Volcano Tea further down the street is independently owned and does not accept the stamped cards from the old place :(
I must also add that I have had one of THE WORST drinks made here. I asked for taro slush sans tapioca and got back a purple snow drink...the consistency was that of mashed up snow. And she did it to my friends drink as well...worst made drinks ever.
