I wish I could give Chatime more stars, but it was just unimpressive for me. I ordered the large pearl milk tea (less ice, 50% sweetness), and there was just way too much milk in it. The entire drink was mostly milk and could hardly taste any of the tea. The pearls were nice and chewy but not too soft or hard, and just the right sweetness to it.
Overall, I'd recommend ShareTea over Chatime.
