Jamie’s, Hooked, Izumi and Chops are open for lunch on sea days. I think Jamie’s or Hooked was open on embarkation when we were on in January.
Book all your reservations as soon as you board or close enough to get the ships Wi-Fi.
You get $20 per person per day at Playmakers and Johnny Rockets. If you go over that then you pay the difference. The JR on Navigator is different, it’s just a counter you order and then go find a seat near the pool. Izumi you have $39.99 for the prix fixed menu.
