The world's largest underwater restaurant in Norway was just included on Time Magazine's "World's Greatest Places 2019" list.

Fittingly called "Under," the restaurant — the first of its kind in Europe — has three-foot-thick walls and is designed to withstand harsh weather and rough seas.

The 110-foot-long structure resembles a giant concrete tube that's half-submerged in the water.

The restaurant, which opened in March 2019, seats 35 to 40 guests each night, who can watch sea life go by through a 36 x 13-foot panoramic window as they eat.

The world's largest underwater restaurant in Norway just earned a spot on Time Magazine's World's Greatest Places 2019 list.

"Under," which opened in March, is Europe's first underwater eatery. Designed by Snøhetta, the restaurant sits half-submerged into the sea and has three-foot thick walls designed to withstand the area's rugged seas.

Guests at Under can gaze at marine life through a 36- x 13-foot panoramic window in the dining room, which seats between 35 and 40 guests each night. Muted lighting was installed on the seabed so that guests can see the marine life in any weather conditions.

The cuisine is, of course, seafood. Danish chef Nicolai Ellitsgaard Pedersen will create locally sourced dishes that include cod, lobster, mussels, and truffle kelp, which is a local type of seaweed that apparently tastes like truffles.
