The rule is, each person must order one thing. So if there's only 3 out of 5 people ordering... that's not good enough, they will insist you order more. However I don't know what happens if you refuse to order.
I used to think this place was a pretty decent place to sit with a small group of 3 or a pair just work on personal things that need a bit of attention, but I've noticed for the number of times I've been here; as soon as the environment gets louder, the music along with it gets louder too. It isn't until you ask them to turn it down they will. Although granted I've always come around the evening.
All and all it is a decent place to meet friends, have lunch or a snack with a side of bubble tea and desserts. The price is a bit higher than other bubble tea places. The menu comes with a large variety of choices with their drinks and food, which is nice. The drinks are a bit on the sweeter side due to them soaking the tapioca in syrup along with the drinks (especially the fruit ones) are made with syrups/purees as well [I think you can ask them to make it half sweet if needed]. Improvements should be made with the staff and consistent cake sizes.
