and you're looking for a nice place to have dinner I recommend trying the Bluewater Grille which is located directly across the street from the aquarium. It's casual dress, no reservations, and reasonably priced but the menu has a nice selection of dishes primarily of fish and steak. I had the Grouper Piccata, the Queen had the Lemon Sole with Brown Butter Sauce. Both dishes were absolutely delicious (yes, we shared). The atmosphere was nice and there was a nice mix of ages and cultures. Overall I give it two thumbs up.
