Was just reading another post that mentioned Tanpopo ramen house in Japantown and recalled how years ago -- at least 6+ years ago -- Tanpopo used to offer gyu-tataki that was absolutely decadent. Unfortunately they took it off the menu, and I don't think I've eaten this in San Francisco since, though I haven't explored as many Japanese restaurants as I'd like.
Gyu-tataki is essentially marinated thin slices of raw beef (perhaps imperceptibly seared), served with a dipping sauce. Sometimes appears on menus as "beef sashimi". When it's good, it's phenomenal.
But most Japanese restaurants don't even offer it.
Any hints on where this might be available here?
