Really! Have you had a peanut sauce at Teppan Edo?
The common dipping sauces at most teppanyaki restaurants is a ginger sauce and a mustard sauce. I thought these were the sauces at Teppan Edo along with another white sauce (that is not a nut sauce). Soy sauce, Teryaki Sauce are also common sauces in cooking, but not peanut sauce!
I have read a recipe for the ginger dressing that is common on salads served at Teppanyaki restaurants that had peanut oil so I always ask, I would never just assume that something didn't contain peanut oil or peanut products, but I have never encountered a Japanese restaurant (teppanyaki also) that uses peanut oil (still always ask though, even if I've been to the restaurant a hundred times).
