Sushi House and Hana Mizuki went through a name change and menu change this past year. As far as I can tell, the upstairs retains the same sushi menu; downstairs is an odd combination of Japanese steak cooked at the table in the center of the room, and a varied Chinese menu at the remainder of the tables. The good news? Whatever cuisine you choose, you really can't go wrong!
The sushi upstairs is my favorite choice. It's a peaceful dining room with lots of wood, paper screens, and pretty quiet. There are charming individual rooms with traditional Japanese seating for parties of 5 or more. It's worth grabbing a few extra people to get one.. Order from an extensive menu of all kinds of Japanese food, including some terrific soups, or order sushi and sashimi a la carte. They do an amazing job with the sushi. There are many tasty sushi choices for vegetarians, and a side dish of edamame for the table is a good protein source and un to eat out of the pod. If you are looking to save some money (and an evening of a la carte sushi with a glass of wine can get fairly expensive) they have box specials, where you get 2 menu items (like sushi, sashimi, treriyaki, etc) along with a delicious ginger-dressed salad, and some sliced fruit, and a bowl of miso soup, all for $15.95.
The Chinese food downstairs is very good; much better than Chang An in Concord Center (though Chang An certainly has a better location.) There are also many vegetarian options, and they are extremely attentive about special diets.
The hibachi is a fun show, way too much food, very tasty, kids love it. Things can get a little noisy downstairs.
The location, just off rt 2, is a bit of a hassle to get to, depending on where you're coming from. It's not really a good walk from anywhere except if you're staying at the Best Western. And the parking lot is not really large enough. I expect people do park in the Papa Razzi lot (much bigger) next door.
