Spend an evening at Matsuhisa Restaurant in Beverly Hills, and you can easily rack up a tab totaling a few hundred dollars. Sushi of this quality does not come cheap. But at the famed chef’s restaurants on the two ships operated by Crystal Cruises, you’ll need to pony up only $7 per person after you’ve laid down your chop sticks for a final rest.

Long a land-based favorite, sushi has returned to the sea at Nobu’s restaurants on Crystal Serenity and Crystal Symphony. And at what a price. That $7 per person? It’s for suggested gratuities; Crystal charges nothing for dining at Nobu’s Silk Road and The Sushi Bar.

“Nobu is about as good as it gets,” says Thomas Mazloum, senior vice president of hotel operations for Crystal Cruises. “His cuisine is unique, creative and healthy, and he has a name that resonates well around the world.”

While Crystal claims perhaps the world’s best known sushi chef, other cruise companies are introducing Asian-themed specialty restaurants aimed at rivaling the best of their land-based counterparts.

When launched in July, for example, Holland America Line’s Eurodam debuted the Asian-inspired Tamarind restaurant, specializing in sushi and sashimi.

For people who love sushi, cruises on these vessels, with rates that range from $100 to $500 per person per day, can prove to be quite a value, especially considering that you could dole out $100 or more per person for similar dining experiences ashore.

And it would be hard to swallow that the sushi is fresher elsewhere than in a restaurant floating directly over sushi’s natural habitat.
