I'm sorry to say that Ichiban is really not a good place to eat. Actually, the whole food court in the mall could be way better on a deeper level! If you're planning to eat here, or really intent on eating here...I would say that their best out of all dishes would be the chicken teriyaki.
On my plate, I had the chicken, noodles, and shrimp tempura. All of it was painstakingly dry and not very well seasoned. None of it was really that warm either. I'm probably not ever going to eat here again. On the plus side, the people working here were very polite and nice!
The food court is one of the worst places to eat in the entire Fashion Show Mall. FSM, please reinvent your FC, because the place is just too big to be -that- bad.
