First of all the ship itself is beautiful, the staterooms are well appointed and bathrooms adequate.
What let the ship down was the niggardly approach to food, you had to request smoked salmon and when you did, you were served a minuscule portion! Sandwiches were a disgrace, thick white bread, spread with margarine and with fillings so sprayed on you could not tell what they were at all!
Cream tea was a disappointment, no clotted cream here only whipped stuff. None of the advertised white glove service either.
Service was mixed. We ate in the Britannia restaurant and had wonderful waiters who really looked after us but I think we were lucky. When we had lunch in there the service was slow and indifferent. The food was okay but not great and there was no everyday choice you could have if the menu did not appeal.
There was very little in the way of pleasant service around the ship, surly was the best description, especially in the Pursers Office where one was met with a blank expression more often than not. Most requests were a bit too much trouble.
All in all we enjoyed our cruise but Cunard need not consider themselves the gold standard, they are very much par for the course cruise wise. It's a shame really, a proud Britsh name has been weakened by American ownership and bean counting. Don't pay top dollar for Cunard any more.
