A Ferris wheel, a train ride, a carousel, dancing fountains and tanks loaded with hundreds of fish -- what more could a kid ask for? This virtual theme park in the Theater District offers a whole afternoon of child-friendly thrills. Think of it as a good, centrally located alternative to Six Flags. The sound and smell effects inside the Aquarium's Amazon River and Mayan Temple attractions intrigue kids in a Disneyesque manner. And little ones can dine at boatlike tables and watch continuous movie clips in the informal downstairs restaurant. Thanks to the Landry's ownership, the food's not bad either.
