Look out alligator might eat you! One of our most favorite sushi rolls at Niwano Hana. This is one of the places to go to for high quality sushi in Rockville. It’s alligator! How can you pass up on a sushi with alligator. Well not real alligator meat. Kind of wish it was. its a giant slab of avocado, eel, shrimp tempura with yummy sauce on top. Great mix of soft and crunch in every bite. Look it sparkles in the light! One of their more pricy rolls, but its worth it.
