New Ginza is my vote for best sushi restaurant in Boston. While Fugakyu shines with its rolls, its sashimi isn't always the best and parking is difficult to obtain. Oishi is orgasmic with a Zagat rating of 29, but it is small and unromantic. At New Ginza, you have room to spread out in their light-wood panelled dining room. The modern, simple decor is a perfect match for the harmonious nature of their food.
New Ginza offers all manner of Japanese food, and often feature exotic chef's creations. This is one restaurant where I always ask what the specials are. At the same time, they offer a consistent selection of creative rolls, or makimono. With a Celtics, Patriots, or a Red Sox roll, you're getting something very special, very Boston. These rolls are big, well worth their price tag. The Goldfish and the Black Dragon are two of my favorites on their makimono list.
After asking after their freshest fish, be sure to order it as sashimi or sushi. The last few times I've visited, they have had white tuna and striped bass.
Food delivery is well-paced. Each plate is designed like a work of art, with a garnish of afalfa here, a volcano of rolls there. Instead of receiving your entire order at once, your order is brought out to you in manageable parts. The waitstaff is observant, bringing your next plate as soon as you are finished with the last.
New Ginza is a "don't miss" for sushi lovers. Reservations are recommended on weekends, but not required.
