I like that they allow you to mix different flavors of teas. I'm from the east valley and not many shops have that as an option.
Also the boba challenge caught my eye. $225 gift card to the shop if you can finish a 2ft 3in glass of boba in 30 mins - or you pay $75. As much as I love myself some boba milk tea, I don't think I'd even be able to make a dent within that time frame! Something I'd definitely be interesting in coming in to watch happen though
