Benihana is a chain of so-called Japanese steakhouses based in the USA, although they have restaurants all over (even Bangkok). Their food is okay, but for the price and all, shouldn't actually try some Japanese food? Seriously, if you have any other options, try something else. Benihana is to Japanese food as ... oh, Olive Garden is to Italian food. Pretty good, but expensive and inauthentic.

Benihana usually is only in reasonably large cities, so if you have one you probably also have some Japanese restaurants. Go there instead.
