Bamboo floors, Japanese antiques and chandeliers grace the main dining room, while silk lanterns hanging over the sushi bar give an exotic feel. Watch while the freshest Japanese delicacies are being prepared, or sip a drink at the bar, where colourful aquatic creatures live in a double-sided, 2,000-gallon (7,571-litre) saltwater aquarium. A variety of sushi, sashimi and specialty hand rolls complement delectable Asian-influenced seafood creations. The menu offers many options to sample a variety of dishes, intended to be shared at the table.
