"Europe's first underwater restaurant, Under, is officially open for business. Designed by Snøhetta, it offers diners a journey underwater as they dine 16 feet below sea level with views of marine life through a 36-foot-wide window. The restaurant aims to connect people with the ocean, and even the building's exterior is designed to attract sea life to purify the water. An 18-course meal with wine pairings costs about $430, and reservations are filled through mid-August."
