If the Teppanyaki location you are referring to is the one adjacent to the supermarket, I used to go to there all the time as it was next door to where I got my hair cut, and they have a dim sum table that I liked. The guy who cuts my hair moved, but I stopped going to the buffet a year or so before that because it was going downhill. Walls and floors were getting dirty, and the other clientele made it a bad experience: one time a group from a local retirement community showed up, and we had to watch some poor guy who just wanted to eat his lo mein in peace get hit on by 4 other seniors who were single and ready to mingle from the same group. The next time there was a bus of Chinese tourists. I went to the restroom to wash my hands and a couple of people stuck their water bottle under the faucet I was using to rinse my hands. Rude! The place is in need of a deep clean or renovation.
Now we prefer the location in Manville. They don’t have any non-Americanized Chinese food, but they do have individual ice cream cups for dessert, which is much less gross than the places with giant tubs of ice cream that you scoop with scoops that are sitting in a water fountain. Barf.
I know this is the NJ board, but today we went to Noboru http://www.noborurestaurant.com/ in PA. We like it a lot: looks to be owned and run by Koreans, and they focus on sushi and Korean dishes. Since it it not NJ you can get beer and wine too.
