Serenitea is one of the more established milk tea shops out there. At P95 for a medium, cold classic milk tea including one sinker (this is a pudding) it's neither one of the cheaper nor more expensive places out there.
This is one of their bestsellers, Nagoya, I think.

I included the chair because I loved the design. I found it very cute :)
