About

In Lilia, in the town of Plouguerneau, the Castel Ac’h restaurant faces the sea and the landscapes of the archipelago head-on. Between Île Wrac’h and the horizon of Île Vierge, the light never stops changing. The setting is already a fine experience, but it is the way the cooking extends this landscape that makes the house so interesting. Under chef David Royer, the plates favour flavour, freshness and pairings built around Finistère produce. Plouguerneau oysters, Iroise fish, langoustines, garden vegetables, herbs and buckwheat can inspire cooking that moves between simplicity and technique. The menus offer several levels of discovery, from lunch to a four-course journey. A walk in Lilia, a view of the Île Vierge lighthouse or a stretch of the GR 34 can come before lunch. Book early for a table near the view; a place on the terrace depends on the service and the weather.
