Kids always love The Treasure Ship. Seafood and service are usually great, but they can be a little pricey depending on what you order.
You could always try Hook's Grill and Grog for lunch and see if you like it enough to go back for dinner. Lunch is much less expensive and it's a lot of the same food. Hook's is upstairs at the Treasure Ship.
Good luck!
