The Pool-side restaurant of Airways is nice for every day meals, they also have "Bacchus" restaurant which is the best restaurant in town, with price according to it's reputation.
An other VERY very nice restaurant is "The Cellar" and it has also a VIP bar quite nice, prices are salty though!
In town, "Itchizen" is a very nice Japanese place. An other one, in Borokko, is "Daikok", great Japanese place.
The " Royal Yacht Club" is very nice for lunch as well, great view on their harbor, but can be hard to get in if not accompanied by a member of the Yacht club.
The restaurant is in the Airways Hotel complex which ovelooks Jacsons International Airport. It has a mock plane attached to the wall. It's very airy and spacious. The food is good.
