Top 10 Underwater Restaurants in the World

Ithaa, a glass undersea restaurant in the Maldives, has been serving meals below the waterline since April 2005 and is still open in 2026. It sits about five metres below the surface at Conrad Maldives Rangali Island and is generally treated as the first all-glass undersea restaurant of its kind ^[1][2].

The category is smaller than older travel lists suggested. Several widely advertised projects were never built, notably the Poseidon Undersea Resort in Fiji. Dubai's Al Mahara, a famous aquarium-view restaurant at Burj Al Arab, has been closed for refurbishment, with reporting pointing to a late-2027 reopening rather than a 2026 visit ^[2][3]. Aquarium rooms that look into a tank from a shopping mall or a hotel lobby are also set aside here, because they are not restaurants placed in the sea.

The ten entries below are places that, as of November 2026, are either operating under or in the water, or are clearly labelled as aquarium-view dining of a distinctive kind. This is a curated list, not an official ranking, and opening nights in the Maldives change with weather, tides and resort schedules ^[1][2].

Key Facts

"Undersea" here means a dining room whose windows look into open water, or a comparable submerged structure. Status is as of November 2026.

Underwater Restaurants at a Glance

1. Ithaa

Ithaa was built on the lagoon reef at Rangali Island and opened on 15 April 2005 as a small, fully glazed room about five metres under the water. The Conrad Maldives still advertises lunch and dinner there in 2026, which is the basic test this list applies: the place exists, and it is bookable ^[1].

Because the room is tiny, a seat is a reservation, not a walk-in, and the experience is as much about the reef around the glass as about the menu. That combination, more than any later copy, is why Ithaa is first. Later Maldives restaurants went deeper or larger, but they followed this model ^[1][2].

The same resort later added an undersea hotel suite, the Muraka. It is not a restaurant and is mentioned only to show that the site has kept investing in submerged rooms rather than treating Ithaa as a closed novelty ^[1].

2. Under

Under, at Lindesnes at the southern tip of Norway, opened in 2019 in a concrete structure that was designed by Snohetta to sit half on the shore and half in the sea. It is Europe's first undersea restaurant and, unlike the Maldives rooms, it looks into cold North Sea water through a large window wall ^[2].

Service in 2026 is still limited and seasonal in part: dinner on selected days year-round, with lunch in the warmer months, according to recent travel guides that checked the restaurant's own calendar ^[2]. The kitchen has been treated as a serious restaurant, not only as a gimmick, which is why it is second rather than a footnote.

Winter storms and water clarity change the view. That variability is part of the design, not a defect ^[2].

3. Subsix

Subsix, at Niyama Private Islands in the Maldives, opened in 2012 as a club and restaurant reached by boat and a short descent to a room about six metres down ^[2]. Recent guides still list it as open, with daytime Nikkei-style dining and evening events, which is a different rhythm from Ithaa's short, formal seatings.

The room is larger than Ithaa and was designed as a social space as well as a dining room. That makes it easier to photograph and easier to book in groups, and it has kept the venue in circulation more than a decade after opening ^[2].

As with the other Maldives entries, operations depend on the resort and on sea conditions. The 2026 status used here is "open and advertised," not a promise about every night of the year ^[2].

4. 5.8 Undersea Restaurant

The restaurant at Hurawalhi Private Island is named for its depth, 5.8 metres, and opened in 2016 ^[2][4]. It is another all-glass Maldives room, larger than Ithaa, and is still listed among the atoll's working restaurants.

Its claim is less about being first than about being a clearly operating, purpose-built undersea dining room in a resort that is still running in 2026. For a traveller, that practical fact matters more than a slightly later opening date ^[4].

Together with Ithaa, Subsix and SEA, it shows how concentrated this category is. Four of the ten entries are in the Maldives because that is where most of the true undersea dining rooms were actually built ^[2][4].

5. SEA

SEA, at Anantara Kihavah in the Baa Atoll, opened in 2011 as an undersea restaurant within a larger complex that also serves food at the surface ^[4]. It remains one of the longer-running rooms after Ithaa, which is a useful test of whether a submerged restaurant is a stunt or a lasting facility.

The Baa Atoll setting, a UNESCO biosphere reserve, is part of the appeal and also a reason to be cautious about light, waste and boat traffic. A 2026 visit should be planned as a reserved sitting, not as an casual drop-in ^[4].

SEA is fifth because it is established and open, not because it is more elaborate than Under or deeper than Hurawalhi. In this category, survival over a decade is itself a ranking fact ^[2][4].

6. Utter Inn

Utter Inn, created by the artist Mikael Genberg on Lake Malaren near Vasteras in Sweden, is a tiny red house whose bedroom and windows sit under the lake. It opened around 2000 as an art project that also offered overnight stays and meals, and it is the opposite of a 200-cover resort room ^[2].

It is on this list because it is a genuine submerged space, older than most of the Maldives restaurants, and still described in recent guides as a working oddity rather than a dismantled installation. Capacity is extremely small, and access is seasonal ^[2].

Anyone expecting Ithaa-style tasting menus will be in the wrong place. Utter Inn is here as proof that underwater dining is not only a luxury-atoll product ^[2].

7. Jules Undersea Lodge

Jules Undersea Lodge, in a lagoon at Key Largo, Florida, began in the mid-1980s as a submerged habitat that became a lodge. Guests scuba-dive to enter, and meals are served inside the underwater habitat ^[2]. It is closer to a hotel than to a public restaurant, which should be said plainly.

It remains useful on a 2026 list because it predates the Maldives glass rooms by nearly twenty years and because it is still operating as a dive-in lodging, not only as a museum piece. The experience is for certified divers, or for people who complete the site's training, not for anyone in evening clothes ^[2].

As a restaurant ranked among resorts it would be an awkward fit. As a historic undersea dining place, it belongs ^[2].

8. Ossiano

Ossiano, at Atlantis The Palm in Dubai, is a fine-dining room whose windows look into the Ambassador Lagoon aquarium, not into the open sea ^[2]. It is included, and labelled, because many travellers use "underwater restaurant" for this kind of room, and because it is a large, still-open example of the type.

It is not the same as Ithaa or Under. The fish are in a managed tank, the building is a hotel, and the drama is theatrical rather than oceanic. That can still be a distinctive meal; it should just not be sold as a reef ^[2].

Al Mahara, also in Dubai, was the older icon of this aquarium style. Ossiano's advantage in 2026 is that it is open ^[2][3].

9. InterContinental Shanghai Wonderland

The InterContinental Shanghai Wonderland, which opened in 2018 in a former quarry in Songjiang, has rooms and public spaces set against a deep flooded pit, including underwater views ^[3]. It is a hotel first, but it has brought under-the-water dining and rooms to a non-tropical, inland setting, which widens the map of this list.

The water is a quarry lake, not a lagoon or the North Sea. As with Ossiano, the honest description matters. The building is real, it has been operating for years, and it is one of the few large submerged-view projects that was actually completed after a decade of renderings from other developers ^[3].

Poseidon in Fiji is the cautionary counterpart: a much-publicised undersea resort that did not open ^[3].

10. Al Mahara

Al Mahara, at the Burj Al Arab in Dubai, opened in 1999 and became the best-known aquarium restaurant of its generation, with a tunnel-like arrival and a circular tank. It is tenth because of that history, and because it is not a 2026 reservation: recent reporting says the room is closed for refurbishment until late 2027 ^[2][3].

Including a closed restaurant is unusual, but leaving it out would hide the most famous name in this category and imply that every entry is bookable next week. The status line in the table is the corrective ^[3].

If it reopens on the reported timetable, it will again be a major aquarium-view room. Until then it is a historical marker, not a travel tip ^[3].

Conclusion

As of November 2026, true undersea dining is still a short list: a handful of Maldives rooms, Under in Norway, and a few older or inland outliers ^[1][2]. Many images that circulate online are either aquarium restaurants, hotel suites, or projects that never left the drawing board.

Anyone booking should check the resort or restaurant directly. Depth, opening hours and even the existence of a room can change, and a list like this can only be as current as the last official schedule ^[1]. Storms, renovations and permit rules have already removed or delayed more than one project that looked solid on a marketing page, which is why the closed and unbuilt cases are named rather than quietly dropped from any realistic 2026 visitor booking list this year.
