I love Japanese food...I spent a couple of years in Japan in my college days. We've been to Plum Garden several times and we had always ordered off the menu. We LOVE the food!
The last time we went we decided to try the Hibachi side of the restaurant. We came away disappointed. The meat was overcooked, the veggies were undercooked, the sauces were mediocre at best. It was a 2/5 experience for us.
If you go, eat off of the "regular" menu rather than the hibachi menu. You won't be disappointed.
