Came here to treat myself after an exam and wanted to have Asian food, but not Dragon I or any of the other downtown Asian food restaurants. I've been to Wasabi once and sort of liked it so I went back.
I think overall the quality is decent. The food itself is somewhat authentic. I tried the Yaki soba (with beef), the Bucky roll, and a small piece of uni. In terms of the sushi, I thought it was pretty good for downtown/state st area. The uni was also good as well. The Yaki soba was excellent, although a little bit on the sweet side. The beef that came with the noodles was very good quality and there was more than I expected. Even so, I wish they would have given more noodles or at least put it in a smaller bowl and priced it as a side. The dish itself came out as half noodles and half decorative vegetable was a little off putting given the fact that it was priced as a 9-10$ entree.
Overall - the assortment of rolls is good. I haven't been here enough to see if they are consistently offered, but props to Wasabi for serving them. For Japanese food, this is as good as it gets on state street (not counting red sushi/ morimoto). In addition, the service is really good and the quaint, peaceful ambience is perfect for a solo diner or friend group.
