I can definitely say I have a soft spot for this place. Their service is fabulous, and their food is even better!! From 5-7:00pm (Tuesday-Sunday) they have $4 appetizers, $5 sushi rolls, and $3-6 beers/cocktails. If you go there, you HAVE to try the pomtini paired with the spicy salmon crunch roll.
Parking is always hard to find, but there's a public parking garage not far from Hamachi (on Civic). If you get there before 6pm, parking is only $0.50 per hour...if you get there after six it goes up to a flat $5/visit, which is still reasonable.
