We had it on our day at sea on the 5/23 wonder. They started taking reservations at 1. I was there around 1:15 and got them, no problem. I think it was 10:30 - 12:30. We got there at 10:30. I was surprised that there were several empty tables. Probably only 3/4 full.
If you get reservations, ask for Michael as your server- he's awesome! We had him for lunch and dinner.
