At the Lancaster, September is shaping up to be decidedly cultural and culinary. The CopperBay Lancaster inaugurates “7 Days, 7 Arts,” a weekly program designed as a journey: each day of the week threads a different artistic discipline, turning the bar into a destination in its own right. Book your September 23 around a menu crafted by Chef Sébastien Giroud. Each month, the Lancaster Hotel opens its doors to creators. A producer, a product, a region, a shared passion.
