This is a unique place! I was pleasantly surprised. They have a few different sorts of tea (green, black, red), and then they can add fruit flavors and "stuff" (like boba). I saw one that looked good, but I didn't want strawberry. No problem! They substituted mango so I had orange, lemon, mango. With a slight carbonation. I really liked it!
Perhaps a tad pricey, but very refreshing. The others in my party were also happy with their choices.
