I’ve only done Chops, Samba and Giovanni’s. Would rank the three in that order.
My wife once ordered the nabeyaki udon from Izumi. It was pretty standard.
Have had Johnny Rockets and Jamie’s (at Yorkdale Mall in Toronto) on land. JRs is fine, but not as an upcharge restaurant. I mean, if Carnival can give us a Guy Fieri restaurant at no additional cost, they can make JRs free.
Jamie’s is not bad. Kids pasta with “Secret Seven” marinara (did not see a “Famous Five” pizza or a Noddy mocktail) is actually quite tasty. Margherita pizza was a super-thin crust, the kind you need to eat with a knife and fork. Adult portions were huge. So I think if you can’t get to a Jamie’s on land it’s worth a try.
