"Moshi moshi!" bellows a voice as you cross the threshold of this oddly decorated Japanese restaurant. That's manager Annop Lasongyang, a.k.a. Nick, greeting you. Often he throws in a "meow, meow!" for good measure. Moshi moshi means hello in Japanese. "Meow, meow?" Well, that's the sound a cat makes. And if anyone knows about great fish, it's finicky cats. Formerly known as Sushi Yama, two-and-a-half-year-old Moshi Moshi, an outpost of the Boca Raton-based sushi house, changed its name a while ago to avoid confusion with a certain similarly named restaurant down the street. The décor mutated a bit, too. Big blue beach umbrellas, a disco ball, and myriad rubber sea creatures and origami birds hanging from the ceiling have been added to the sedate blond-wood room. The thumping disco music, big televisions, and rubber lizards guarding the top of the sushi bar remain, though, as does the friendly service and consistently fresh fish. On the menu: a mouthwatering array of ordinary sushi à la carte, everyday rolls (spicy tuna, smoked salmon), exotic special rolls (e.g., salmon, tuna, yellowtail, avocado, and scallions wrapped in buckwheat noodle), and even what they call super rolls (e.g., chicken katsu, lettuce, avocado, cucumber, and mayo), always expertly prepared and temptingly tasty. Leaves little question that Moshi Moshi is the cat's meow.
