One thing we didn't expect or experience elsewhere in noumea was really bad food,in a weeks dining le fun beach was by far our worst experience, from the looks on the faces of the diners around us we were not alone. We ordered duck and a schnitzel they arrived within a few minutes of ordering and had clearly been reheated rather than cooked fresh. The schnitzel was like eating an old boot the duck only marginally better the French fries were edible (just) so we didn't leave completely famished the green beans were limp and overcooked.
The location however is probably the best in the southern suburbs of noumea with great views over the bay and of ile de canards.
My tip would be to stop and have a glass of champagne or cocktail but not eat there
