I was visiting friends in my old neighborhood over thanksgiving, and went to Samurai on N6th for sushi. Wasn't too keen on the idea, now that I'm surrounded by great Japanese in San Francisco, but it was surprisingly good. I'd recommend the Black Pepper Tuna Tataki appetizer. It's covered in cracked pepper and just slightly seared - thinly sliced but you still got a good bite of the pepper. Looked like they had several kinds of tataki - maybe its their specialty? anyway, thought I'd report on what I thought was an unlikely gem.
