We took the kids to the aquarium at the California Academy of Sciences. We picked up the scavenger hunt which was interesting and educational. And there were penguins. But after visiting the Baltimore Aquarium so many times, I just wasn't impressed with it. They have a nice gift shop.
The Metreon Marketplace was great fun for the kids. I thought I would never get them out of the Sony Playstation store. This was video game mecca. They spent an hour playing the various games. I appreciated the fact that the security people keep a watchful eye on children. They don't allow anyone under 18 to play the M games and they require an adult to be in the store at all times with anyone under 16. Across from the Playstation store was Sony Style which is full of electronics. All the latest stuff, very pricey, and a great place to dream about stuff you would buy if you had the money.
We had dinner at Cioppino's at Fisherman's Wharf. The food was fantastic. Seafood and Italian so everyone was pleased. Service was excellent.
