I had hoped that Grand Blue would address some of their "rough edges" but they haven't. However, I would still have rated them 5* if there hadn't been such serious problems with the food this last trip.
1. Barramundi a la plancha was undercooked. About 1/3 of it was raw and inedible (this fish is very chewy when raw and cannot even be cut easily).
2. The "swiss chard and black-eyed peas" dish was just swiss chard - no peas -- BUT they made up for it by adding another ingredient, namely small pieces of foreign matter which appeared to be parts of a broken dish or fixture.
3. The flan dessert was frozen so solid that it could not even be cut.
These problems are so serious, in my mind, that a one-star review would be called for, but the servers continue to be exceptionally pleasant and helpful.
