I get sushi from the Fusion grocery store just up the street from this Ninoen location. My husband and I have been getting sushi from Ninoen the last couple of times to try something new.
It is a "Take Away" sushi spot (no seating and a grab-n-go place). I eat primarily salmon sashimi and this is my bar on all quality of any sushi spot. For a "take away" local option in Sheung Wan, I think the quality and freshness compared to the Fusion grocery up the street where I most commonly "take away" is pretty similar if not a touch better. Prices are in line with what I would pay at Fusion too. In addition to sushi or sashimi, they have rice's, maki, hand rolls, sets, tempura, snacks...maybe 200+ options on their menu.
So although both are pretty good in the "grab-n-go" sushi options in Sheung Wan, I would say Ninoen beats Fusion by a sliver...the quality is a touch better. read more
