L'Atelier par Yao is a French restaurant in Taichung, Taiwan, and the useful context is what kind of evening it seems built to deliver. The draw is sauce work, technique and carefully composed plates; at a polished mid-to-high price point, it should be judged as a polished dinner worth planning ahead for. Its one-star standing makes it a serious address: polished enough to plan around, but still best judged by whether the kitchen's point of view matches your tastes.
