Domaine de Châteauvieux is a French restaurant in Satigny, Switzerland, 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 luxury, special-occasion price point, it should be judged as a deliberate destination meal. 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.
