Our waiter in the main dining room was excellent - when he asked how our meal was (and he always did), if your response was not excellent or great, he would bring you your second choice from the menu. The food was very great - all the dishes were well presented and proportioned. We have been on other cruises where they seemed to want to fill the whole plate.
Our favourite place was the Martini Bar - Our waiter 'Dwayne' was a delight. On our second evening in the bar he knew our names and always greeted us. He took care of us every evening from then.
All I can say - This was our favourite cruise and will be booking with Celebrity again next year.
