Location: Chatan. From the 58, turn onto 23 (heading east). After Eagle lodge, take the first right, where the sign directs you to Chatan high school; it's on the right hand side, just after the turn, with red lanterns out front. Park under the building, at the spots with the red sign with complicated kanji.
Here is the 2001 Japan update review: http://www.japanupdate.com/?id=3091
This is an unpretentious restaurant, filled with Japanese families when we went. Lunch (on a Sat) is buffet-style for 800Y. The food is a strange combination of Chinese and Japanese influences. Salads include the typical lettuce/cabbage salad with Japanese dressing, macaroni salad flavoured with dill, and a nice sweet sesame bean sprout salad. We did not sample the egg drop soup. Warm dishes:
Yakisoba - strangely sweet and tasted of cinammon, but had lots of vegetables and was not excessively laden with oil
Fried rice - light, with lots of veggies and specks of ham
Sauteed greens - bok choy in a mild sauce, could have benefitted from more garlic and ginger
Shumai-shaped dumplings - filled with a strange concoction we can't place, probably beef in flavor but had a sticky-starchy element that was hard to get off the roof of your mouth. Pretty terrible actually.
Stewed pork with daikon and carrot - flavorful, tender chunks of pork with yummy stewed veg
Egg and something (meat? meat substitute?) in sauce - unusual, but not bad
Sweet potato croquettes - deep-fried and caloric with that artificial-looking spiky brown crust, but the sweet potato filling was tasty
Desserts: white jelly squares with canned pineapple, a mini lemon cake, coconut mochi ball, and sesame mochi ball, all interesting but none made me want seconds
Although some of the dishes were not great, for the money it was fun to sample such an unusual array of dishes. We enjoyed the heavy emphasis on veg. And you don't need to eat for the rest of the day.
