I've always enjoyed Ichiban. I've only been to the Robinson location so I can't compare it to the other locations in the area. I personally believe that the hibachi chefs put on a great show.
My go-to is the hibachi chicken but I've also tried their shrimp & lobster. The hibachi meals come with soup, salad with their delicious dressing, noodles, rice and your meat choice (or there is a veggie option) I'm literally obsessed with the shrimp sauce.. yum!!
Service from the servers are sometimes spotty. Friday when we were here, i think the girl became overwhelmed. She messed up some drink orders & forgot others. the next thing you know a new server came along. The hibachi chefs and the food make up for the servers.
I've never tried their sushi so i can't comment on that. I love the hibachi meals so much that i just stick with them.
