to see the standard RCCL dinner choices. These may have different names now, and some items may have been moved around to a different night, but are pretty much the stock offerings for RCCL.
The kid's menu is the same for every night, as you'd see in a shore restaurant. Chicken fingers, pizza, hot dog, hamburger, etc.
Also note that RCCL has standard alternate choices like a steak, salmon fillet, and I think a pasta dish, every night.
