I'm glad to have been able to help you identify the type of table you
were looking for. The table is called a "teppan table" or "teppanyaki
table." These communal tables are often long and straight, but they
are sometimes round, or may be in the form of a counter that resembles
that of an American diner.
"Teppanyaki or table top cooking style claimed to have started in
Japan around 1945...In the hand of a skillful chef freshly seasonal
food cooked on teppanyaki table where dinner sit around is an exciting
In Japanese, teppan means an iron plate or a steel sheet, and yaki,
stir-fried food or stir-frying. Teppanyaki is stir-fried meat and
vegetables cooked and eaten off a large, table-top grill.Teppans are
made of stainless steel of varying shape and size. The Teppanyaki
table generally consists of a large rectangular steel plate surrounded
by a table surface on three sides where the guests sit and eat. The
fourth side is where the chef prepares the meal in a most enjoyable
way. A large teppan, including the surrounding counter from which
diners eat, can seat as many as 20 people
In Ichioku Teppanyaki, one of the teppan tables is long enough to
serve 15 people. With three gas burners operating along the teppan
plate our skilful chef can cook all the meals at the same time."
