I vote for Kona. Very good food.
Yes, Boma is a buffet and there is some variety, but only my DS11 really liked the food. The prime rib was good, but the rest of it was not my taste. I'm not that picky either nor is DH. DS8 had some of the kiddie foods. It was crowded and involved lots of time waiting for food I didn't like. We didn't have a good server (and read from others on the board that this particular server is known for this, but that was ONE server). Our family won't return to Boma and I'm not even glad I tried it. Sorry to be such a downer, but am providing my honest opinion. Of course, others LOVE it and it is a must do for them.
