What customers say?

“ It’s a French restaurant but it has an extremely strong Japanese influence, which is why most Japanese will like it (less sure about the French). Product quality is high and I was personally pleasantly surprised by the appetizers. ”

“ 【至福の食体験】本年、最も心に残ったレストラン。 元・英国大使館の料理長を務められた佐藤シェフが腕を振るう名店が半蔵門にあると伺い、念願叶って訪問いたしました。一口目から、その卓越した技術と深い味わいの虜となりました。 まず、コース序盤に供されたコンソメスープ。黄金色に澄み切った一滴に宿る、深く滋味豊かな味わいは、身体の隅々にまで染み渡るかのようでした。この一杯で、私は完全に魅了されてしまいました。 メインの「ほほ肉の赤ワイン煮」は、ナイフが不要なほど柔らかく煮込まれており、ベルベットのようになめらかなソースは、何層にも重なった複雑な旨味の結晶でした。家庭では決して到達できない、まさにプロフェッショナルの味です。一口ごとに、その完成度の高さに感嘆いたしました。 名物の「スイカのケーキ」は、遊び心と緻密な計算が両立した見事なデザートでした。そして、締めにはシェフの故郷である山形県産のお蕎麦が。フレンチのコース後とは思えぬほど、清涼感があり、すっきりといただくことができました。 料理の素晴らしさは言うまでもなく、佐藤シェフの温かく実直なお人柄が滲み出る、心地よい空間もこの店の大きな魅力です。心から満たされる、至福の時間を過ごさせていただきました。 半蔵門という場所で、これほど質の高い食体験ができたことに深く感謝いたします。特別な日や、本物の味を求める方に、自信を持ってお勧めできる名店です。 ”

“ 麹町にオフィスがあった頃、夏の楽しみはこのお店の「スイカケーキ」。 ランチタイムに本格フレンチのコースを味わえ、しかもデザートでスイカケーキに出会えるなんて贅沢すぎます。 見た目のインパクトだけでなく、食べてみると驚くほど軽やかで、ほんのり効いた塩気が甘さを引き立ててくれる。重くないから最後まで幸せに食べきれます。 季節限定ですが、毎年心待ちにしていた特別なケーキです。 ”
