We just did Aqualuna followed by Hutong for dinner. I wasn't overly impressed with Hutong (over priced average food, had to ask for 3 different white wines before they had what we wanted, very very average service) but the views were great. I've heard dinner at Aqua is better.
Just my opinion, but I have been to Aqua 3 times and each time the food was average quality, vastly overpriced, and service was terrible. Nice view but that's about it.
