This place sucks but unfortunately it's your closest ayce option near Eaton's Center. I'd suggest making the trek and walking to Aji Sai instead!
Spring Sushi is overpriced, coupled with mediocre sushi, and poor and slow service. There's empty tables all around but you can still expect to wait half hour to be seated. Their other offerings like rice or udon or any soups is extremely salty and doesn't really boast any true taste at all.
If you're looking to really delect in some true sushi, this isn't the place. You'd only go to Spring Sushi if you're too tired from shopping across the street. I would give them props for a clean location, spacious seating, and if you care about it, an iPad ordering system.
If I were you, I'd just spring away from Spring Sushi.
