I lost in the NCAA pool to my girlfriend, so now I have to buy her dinner. I'd probably be buying anyway, but now she gets to gloat about how bad my picks were. Anyway, she wants sushi, and somewhere downtown - close to Downtown Crossing (we are going out there afterwards). What is a good place to go with some ambience but that isn't going to take a big chunk out of my wallet (i'm not cheap, but i'm also not rich). Any suggestions? If there are any other places that are close to the T, that might work as well.
Thanks in advance.
