I've been to this place a couple of times for a quick and semi healthy dinner when I'm near campus. I always get the hibachi chicken. Which is just okay.
Pros:
They always give a good portion
It's always hot and made to order
The price isn't bad, though it's not great either
The chicken is tender
Cons:
The sauces are lackluster and watery but necessary because...
The food is grossly underseasoned
The wait times are longer than most because of the amount of take out orders
They have only one cook to fulfill hibachi orders
The decor is hideous, dated and dusty.
The rice isn't really fried on the cooktop with your order and maybe not at all because the texture is off though less noticeable when you add the sauce
I think that Hanaya has potential. They just need to make some tweaks to improve the food and interior. Good in a pinch but not a destination.
