Nigiri Grand

I believe there may be a slight misunderstanding in the name of the sushi dish you are asking about. Based on my knowledge of sushi, there is no particular type of sushi called "nigiri grand." However, there is a type of sushi called "nigiri" that is commonly found in restaurants in the USA.

Nigiri is a type of sushi that consists of a small mound of vinegared rice, topped with a slice of raw fish or seafood. The fish or seafood can vary widely, and may include tuna, salmon, shrimp, octopus, or other seafood. Nigiri is often served with soy sauce and wasabi on the side.

There are many variations of nigiri, and the presentation can vary depending on the chef and the restaurant. Some nigiri may be simple and straightforward, with just a slice of fish on top of the rice, while others may be more elaborate, with garnishes or other decorations.

Nigiri is a popular type of sushi in the USA, and is often considered to be a more traditional or authentic version of sushi. It is a great way to experience the fresh, delicate flavors of the fish and seafood, and is a favorite of many sushi lovers.

I hope this information helps! If you have any other questions about sushi or other types of Japanese cuisine, please don't hesitate to ask. I'm happy to help.
