Chez fyfy is a Japanese restaurant that gives Lyon, France a clear reason to appear on a dining shortlist. The draw is seasonality, restraint and precisely controlled pacing; at a comparatively accessible price point, it should be judged as a smart choice when you want something considered without turning the night into a major splurge. It is most compelling for diners seeking precision, pacing and quiet focus, especially if the night calls for something more considered than a safe default.
