We're cruising on the Atlantica in January and have read and heard very poor reviews about the food. We are not fussy eaters but do like a quality level meal - like one would expect at a fine restaurant. I've heard that the pasta on Costa is dry, cold, and the same everyday. I've heard that the meals overall are mediocre at best - again compared to a 3 or 4 star land restaurant.
I've love to hear from those who've been on Costa, esp. the Atlantica on their view of the food. Naturally, even in a great restaurant sometimes you get a bad meal - but I'm talking about - overall - on a 7 day trip, the good should outweigh the poor.
