I went to lunch at the Hyatt the day after it opened. I went to the buffet-type restaurant which has appetizers and desserts on a main table and the main dish a la carte. The main dish was a bit small but delicious. The desserts were the best I have had in a while. The service was incredible, almost too much!! Lunch was only $25 per person.
I have not tried the main restaurant yet but will post when I do. I live in BA so if anyone needs anything prior or during their visit, feel free to contact me.
