I've been here twice and the experience was a bit better the second time around, but not by much.
The first time I came was during the grand opening. We saw the "buy one get one free" sign and had to see what was there. Little did we know, this promotion was just the house milk tea. We were unaware of this until we got excited about the drinks we chose and our bill came up to $14 (we ordered chicken, too). We were THEN told about what the BOGO included. My sister and I were disappointed and she canceled our order completely to go somewhere else.
I came back a second time to give it another chance. I was thrown off by the fact that it's a restaurant type theme where we order at the counter and pay BEFORE we leave. I almost forgot to pay because I'm used to paying for my drinks right after ordering. I would be less confusing if there was a sign telling us to "order then pay before you leave" or "please wait ot be seated" or maybe someone at the door to direct us... maybe that's just me.
I wanted to try that matcha espresso drink but was really nervous to do so. My friend ended up getting it so we can both try it and I stuck with my hokkaido milk tea (had to stay in my comfort zone because I'm too embarrassed to ask for a redo on a drink I don't like). I took a sip of the matcha espresso and immediately regretted it. Matcha and espresso is probably a combined taste that you must acquire. I also wasn't very fond of my hokkaido milk tea; I've definitely had better and I will most likely stay with where I know I won't be disappointed.
