We were visiting our daughter and Ace's is one of her favorite places in the Marina District (and the City as a whole). We love Japanese food and have been lucky to have eaten in some of the very best places in Japan. Ace Wasabi would give many of those places a run for the money. We sat at the bar (it was a last minute decision and all the tables were taken) but one ought to eat sushi at a sushi bar. The gentleman who "served" us --made our sushi and rolls was very good at his "job". When we were ready for our next order, it was ready for us. All in all, a delightful evening We had eel, tuna, trout (rolls and sushi) and California rolls. The seafood was excellent, fresh, good sized proportions.
