Three of us went to SI last night. Sat at table, ordered omakase sushi-sashimi assortment, requested focus on the specials. We were completely wowed. Yes, everything was fresh and high quality, but the thing that made it stand out was the composition. How each one-bite combination of fish, dressing, and rice blended so perfectly. Standouts included marinated tuna, marinated and torched sablefish, chopped and dressed aji. Everything at just the right temperature, not too cold, which is especially important with fattier fishes. All very light and clean, yet certain bites had a very intense savory flavor, for which I give the rice much credit.
This is an unflashy, very restrained style, and each bite is on the small side. We were still hungry after we'd finished the sushi and ordered some kitchen specials. Fried spicy octopus, and whiting tempura, both delicious.
We are experienced sushi eaters, generally disappointed with the level available in the Boston area, and were totally raving about this place. The suburban location probably prejudiced me, but I really was not expecting SI to live up to the reviews, and it most certainly did. Total bill with sake $224 before tip, quite reasonable.
