The average Yelp rating is 3.5 stars, and I wholeheartedly agree with the consensus.
This Ichiban has been in business for as long as I remember the Richlane Mall is opened. I have patronized here numerous times over the years. I believe the one undeniable strength of this restaurant is consistency. The raw fish in sushi and sashimi has been reliably fresh. The fish quality is similar to a good AYCE or slightly better than an average AYCE. The rice has always been supple. The portion is never large or small, just reasonable for an average person. If you are a big eater, prepare to order an appetizer or a roll on top of a sashimi or sushi order. The services is not super fast or attentive. When they do wait on you, the wait staffs are courteous. The waitress is often sensitive and patient with the needs of the children who dine with me, such as warm water not cold, nothing raw, nothing spicy, take forever to go through picture menus, etc...
3.5 stars for food, services and decoration. 0.5 stars for consistency.
