Service is a bit slow, but when we got to the front of line we know why -- cashier was very friendly and helpful in answering our questions about the drinks (the names of the drinks are not very descriptive) and offered us free milk tea and tapioca samples to try. I got the Royal no 9 drink, which taste very different from other bubble tea places. Not as milky, a nice refreshing tea flavour. Made the wait worth it!
