If Wes Anderson made a hotel, it might look like this. Perched on a cliff overlooking Biarritz Bay since 1907, the Regina Experimental pairs Belle Époque grandeur with playful Art Deco design by Dorothée Meilichzon: think aquatic carpets, rich maritime blues, and a soaring glass atrium. Chef Grégory Marchand runs the restaurant, serving Basque-inspired plates on a panoramic terrace with lighthouse views.
