We went there for lunch and find it overpriced. The grilled beef rice has 5 slices of meat on top of a bowl of rice for 15 dollars. After tax and tip it's 20 dollars for 5 slices of meat... I think it's way overpriced.
Be prepared to pay for the decoration and atmosphere. I didn't try their bubble tea but I saw them using generic stuff from big jars that you can buy from any Asian market.
