The taro milk boba is good. You can't choose the sugar percentage here so you're at the mercy of the staff in terms of sweetness, however, mine was mixed quite well. At first I was told they were out of boba, as they make it in house and it takes one hour to complete the whole process (and they didn't predict being so busy that day) - but after guilt tripping the host about hearing this place was the best in Madison, he checked in the back and came back with a smile stating they think there is just enough left for me to try. His customer service skills were on point.
I also ordered the chicken gyoza and definitely think it's appropriate to just stick to the drinks when at Jade Mountain.
I can't get the red bean boba from Cali out of my mind, I'll have to try a couple more drinks from Jade before I can consider myself a fan.
