Captain Picard felt the replicators did not do the dish justice, and always tried to keep some on hand. Q, on the other hand, had a considerably less favorable opinion of the dish. ()

In 2370, Counselor Deanna Troi, beginning to feel the initial effects of her transformation from the intron virus that caused Barclay's Protomorphosis Syndrome that was spreading on the Enterprise-D, ordered caviar for lunch, craving something salty. ()

In 2377, after spending time inhabiting the body of Seven of Nine, The Doctor complained that she denied herself the luxuries of life, telling her that "Instead of replicating caviar, you choose nutritional supplement 13-alpha." ()
