I sailed on the Ryndam Sep 2010 and my experience was very similar to Alan's. I did eat in the PG and my cabinmate said it was the only good meal of the cruise. The meals in the Canaletto were satisfactory and the MDR were mediocre.
After such an experience I too have vowed not to sail HAL again.
I do not have Alan's extensive experience of cruising so I always give great weight to his measured comments. I honestly thought it was just me and possibly high expectations. BTW I am not a foodie but I can cook better.
What puzzles me is the suggestion ' give HAL another go ' - sorry why waste even more money on a mediocre (IMHO) cruiseline? I don't go back to a restaurant if I have been served a poor meal.
Alan's Ryndam cruise sailed from Dover in the south of England. HAL are hoping to increase the number of British cruisers - their report card should be marked must work a lot harder.
