If there's a line, it's probably good - seems to be the thought process in Taiwan. Soft serve ice cream made in house, serving 2 rotating seasonal flavors. Parent company (NINAO) is award winning. We had watermelon (with mint) and hojicha during our visit.
Grab a number and don't wander far. If you miss your chance to order, you need to start over. We were "fortunate" enough to have less than a half hour wait, midday weekday. Can't imagine what a weekend or holiday would be like. Cute shops in the area.
Verdict? It's ice cream.
