As far as I know, those stores are just gone. They may relocate to other parts of Orlando, but in the case of Disney Worldport, it is done. The CMs are being relocated to other merchandise areas, such as Merchant of Venus.
Pac-Man Cafe has good food. I went there once prior to yesterday and got the Macadamia Crusted Mahi which was excellent. This time I decided to try one of their pizzas and got the taco pizza, which was good. My wife got the cheeseburger pizza, which wasn't bad, but when they say cheeseburger, they mean everything you would get on a cheeseburger, including chopped pickles, so the flavor was thrown off slightly by that, IMO. The good thing is, every meal an adult buys, makes for one free kids meal, so our two kids ate for free. The do offer a special deal on the cards they use for the arcade upstairs if you eat at the cafe as well, which is pretty cool. I think its something like $5 off the price of the 2 hour game card.
