The choppy waters off Norway's coast may not seem like the most relaxing dining atmosphere, but thanks to the work of the architecture firm Snøhetta, the North Sea is now home to the region's hottest new restaurant. Under, Europe first underwater restaurant (and the world's largest), opens next year, as Forbes reports—and reservations are already filling up fast.

From the shore, Under looks like some sort of toppled ruin jutting out of the water. Guests enter at sea-level, then descend to the champagne bar and finally to the 100-person dining room, which is submerged 18 feet beneath the ocean's surface. From their seats, diners can gaze through the restaurant's 36-foot-by-13-foot panoramic window. Lighting installed both inside the room and along the seabed outside illuminates nearby marine life, providing a stunning underwater show any time of day or night.

In addition to designing Under to be a breathtaking experience, Snøhetta built the restaurant to durable. The building's 3-foot thick walls protect guests and staff from water pressure and violent tides. The architects were so sure of the restaurant's safety that they intentionally built it in notoriously rough waters near the town of Båly off Norway's southern coast. According to Snøhetta's senior architect Rune Grasdal, a storm is the best time to dine if guests want a truly dramatic view.

The over-the-top atmosphere will be accompanied by a world-class meal. The seasonal menu comes from Danish chef Nicolai Ellitsgaard and dishes are served over the course of three-and-a-half to four hours.

Under doesn't open to the public until April 2019, but the restaurant is already taking reservations. Adventurous diners can attempt to book a table here, or, for parties larger than eight, email the restaurant.
