I had dinner there in September with a friend and we both really enjoyed it. It was the best meal of our trip. The whole fish (yellowtail snapper) was excellent. I did a review of it which you can read via the link in my signature, if you want.
I don't know what's up with the salt, maybe a new chef? That was not the case for us, and I am a light salter at home, so restaurant food usually does taste overly-seasoned to me, but I didn't notice any such thing at Kouzzina.
I am hoping to try their breakfast next trip.
FWIW, I think there are some places where you see many, many bad reviews, very few good ones, and it pays to stay away. Then there are others (like Kouzzina) where you see reviews all over the place, and it is probably mostly a matter of taste. If the type of food at that particular restaurant appeals to you, then it is probably worth a try because you might be one of the ones that love it.
