At La Réserve Paris, an understated luxury hotel near the Champs-Élysées, La Véranda invites sailors and ocean lovers into its ephemeral seaside restaurant conceived by three-star chef Jérôme Banctel. Under the expansive glass ceiling, overlooking the leafy patio, the spotlight is on fresh seafood, a generous caviar menu, and reflective cocktails, all vying for attention until April. A high-fashion coastal escape.
