Manyo has been around since the 80's, but about 10 years ago they got a new owner who made some changes, all for the better.
They have an extensive all you can eat menu ($18.95 for dinner after 5 every day) that includes a variety of sushi, sashimi, various maki rolls, hot foods like baked oyster, miso, gyoza, karaage, tempuras, and a bunch of other things. LOTS of items for your 19 bucks.
The quality of the ingredients is very good, super-fresh, and the sushi is made with workmanlike skill. This is not Tojo's, but it has none of their attitude either. The restaurant is very clean, and the staff are attentive. I have never had a bad experience at Manyo, and because of all the menu choices, I usually eat until I am about to burst. It is all good.
Best of all, you can eat as much sashimi as you want. But if you load up on that, you'll miss out on all the other tasty foods.
