We were there in September on a quiet day mid afternoon and just walked in, there were only 3 or 4 other families in. This was our most expensive meal of the holiday ($95 2 adults 2 kids meals, desserts and drinks) but food was more upper class than most places over there and the setting made it definitely worth it - thought we were on a James Bond set! Kids fries came in a shark pot which we got to keep.
One word of caution - I ordered tuna (lovely) and then felt uneasy about eating it with all the large fish swimming next to us!!!! Next time I'll order chicken!
