Teppanyaki..........we ate there when my oldest was 4. It was okay, he liked watching them make the food........I worried the whole time that he'd reach out and touch the hot plate. I guess it wasn't too great as we haven't been back, but it doesn't stand out as bad.
Nine Dragons.....haven't been.
Coral Reef.....one of our favorites! Our kids love the giant tank, and the way it feels like you're going under water when you come in through the waiting area. They love the Nemo statues outside, too. We had a great lobster soup there. The meal was fine, but the soup was outstanding. We enjoyed the themed desserts, too. Our kids loved it. They had drinks with light up ice cubes, and great desserts. They got dolphin rim-sitters on their drinks. The server paid lots of attention to them, and even pretended he didn't notice when one son switched seats and tried to serve the kids' meal to mom, and mom's to the kid.........my kids thought that was hilarious.
My older son and dh liked the "fish spotter" chart, and tried to name all the fish. Next time, though, we will wait for a table right by the tank. We didn't know to do that, and were on the third tier........while we could see the tank perfectly, the kids would have loved to be closer.
