I haven't tried it myself yet but I've heard Typhoon is good (expensive though) http://www.typhoonboston.com/
Check the hours if you're going there though -- I remember the one time I tried to go, they were closed at a time when it seemed to me like a restaurant would be open, but I don't remember what time that was and it was a couple years ago.
Trident isn't bad if you're short on $. You can basically design your own tofu scramble. Definitely not the most exciting but I've never been sad that I went there, and it is RIGHT there if convenient location is a priority.
