EXPOSITION PARK. [Portions of the museum are undergoing renovations expected to be completed in late 2010 ­ please call for details before visiting.] When in LA, a visit to the Natural History Museum is a must. Well-known for detailed exhibits of North American and African mammals, the museum also has a fascinating marine life exhibit that includes Megamouth, the rarest shark in the world (only 17 have been found since 1976). Dinosaurs are perennial favorites, but don’t miss the Hall of Birds, the insect zoo, or the Discovery Center, which offers lots of hands-on activities for kids. The Wolfgang Puck-affiliated cafe serves signature pizzas and also offers a children’s menu and play area.
