Ok the menu is a little weird, a couple of $30 entrees, but the rest $12-18 plus various pizzas, not a ton of variety. BUT, being in Hawaii, try to get away from upper $28+ entrees with not much of a view. Rays has a SPECTACULAR view (especially seeing the sun set), and the food (price and quality) is reasonable. If you set your expectations correctly you will walk away with a smile on your face and feel like you had a superb Hawaiian experience.
As far as the Rays go, I saw the boats with all the swimmers behind them, took a few looks, can't say that I saw any rays.
