If you like to try the specialties I think it is worth it on Navigator. Hooked, Chops, Jaimies, Izumi, Johnny Rockets, and Playmakers all included. On sea day and embarkation days Hooked, Jamies, and Chops will be open for lunch. On port days Johnny Rockets and Playmakers serve lunch. So that is 8 meals.That being said, the MDR is also good, Windjammer buffet is fine, and free El Loco Fresh is also very good. Promenade has pizza and nice small offerings. Room service is reasonably priced.
