Teppanyaki

“Teppanyaki” (or “teppan-yaki”) is a Japanese cuisine where food (such as steak and shrimp) is cooked in an iron plate (“teppan”) in front of diners. The Benihana restaurant chain made teppanyaki popular in the 1960s.
   
Cho-Cho restaurant in San Francisco, California, was associated with Benihana and probably introduced teppanyaki to the United States in 1961. “CHO-CHO, 1020 Kearny (EX 7- 3066). Affiliated and importing the Chefs from the famous Benihana in Tokyo. Offering for the first time in the U. S. beef cooked in the shabu-shabu manner and teppan Yaki at Hibachi tables” was printed in the San Francisco (CA) Examiner on October 5, 1964.
   
   
Wikipedia: Teppanyaki
Teppanyaki (鉄板焼き teppan-yaki) is a post-World War II style of Japanese cuisine that uses an iron griddle to cook food. The word teppanyaki is derived from teppan (鉄板), which means iron plate, and yaki (焼き), which means grilled, broiled, or pan-fried. In Japan, teppanyaki refers to dishes cooked using an iron plate, including steak, shrimp, okonomiyaki, yakisoba, and monjayaki.
 
The teppanyaki grills are typically propane-heated, flat-surfaced grills, and are widely used to cook food in front of guests at restaurants. Teppanyaki grills are commonly confused with the hibachi barbecue grill, which has a charcoal or gas flame and is made with an open grate design. With a solid griddle-type cook surface, the teppanyaki is capable of cooking small or semisolid ingredients such as rice, egg, and finely chopped vegetables.
   
Origin
The originator of the teppanyaki-style steakhouse is believed to be Shigeji Fujioka of the Japanese restaurant chain Misono. The restaurant claims to be the first to introduce the concept of cooking Western-influenced food on a teppan in Japan, in 1945.

Cho Cho Restaurant Is Japanese Food Favorite
With so many Japanese restaurants popping up in and about the Bay Area, it’s time to call attention to James Sakata’s Cho-Cho restaurant, which will be one of your favorites once you’ve tried the authentic Japanese cuisine. The Cho-Cho is justifiably boastful of its Tempura bar (one of the culinary marvels of Japan). Being located in the dining room, makes it possible to bring the incomparable deep fried (in a light batter) food directly to your table at the height of its taste perfection—the moment it comes out of the bubbling nabe.

The Cho-Cho is more than a local restaurant. It is associated with Tokyo’s Benihana, a “blue book” name in Japan’s “Who’s Who” in the restaurant world.

Something new in Japanese food is teppan-yaki at the Bamboo House (7175 Sunset Blvd., just west of La Brea). Steak, chicken, and lobster are broiled at your booth on a panel of stainless steel in the center of your table. It is prepared by Japanese college boys in happi coats, making the Bamboo House the only Japanese restaurant in town with boys, rather than girls, to cook for you. “Teppan” means steel (or iron) panel while “yaki” is familiar to everyone who has eaten sukiyaki, teriyaki, or batayaki.

Teppanyaki steak isn’t Kegon’s creation. But the classic taste we give it is. We use only prime beef — the finest. We cook it right at your table, with a masterful flair. And our sauces are something else again.
