This Mahiki location was located at the Forte Village Resort. It appears to have been open from 2017 to 2018 or possibly 2019 before it closed.
Promotional materials show a beachfront open seating terrace bounded by glass dividers to block the wind/ocean spray. Arching trees were strung with lit fish floats. The bar was a small open-sided structure facing out over the seating area. The attached youtube video gives a better idea.
In addition to this Mahiki location, there were also the original London and the Manchester locations (both now closed), one in Dubai, Arab Emirates (now closed), the Mahiki Beach location in Marbella, Spain (open), and a second London location (Mahiki Kensington, closed in 2019). There was also a Mahiki club in Gothenburg, Sweden (closed).
