I have eaten on it twice. That was some Amazing food.
2,300 diners at a time is crazy for the US (except maybe Las Vegas buffets), but this was indeed as much a tourist attraction as it was a very good restaurant.
A friend had eaten on the ship and thought that they did a very good job, considering the obstacles the crew and cooks faced.
I also dined there over the years. I passed by it on ship every time I came into Hong Kong. To me that restaurant was Hong Kong.
