I'm going to Nobu for lunch on Thursday with my fiance. I've never been there before, so I have no idea of what the dress code is for lunch there. I'm assuming that T-shirts and jeans are right out, but I'm not quite ready to go out and rent a tux either. Where are the safe zones in between these two?
Also, what sort of specials does Nobu normally offer for the $20.02 lunch (carried over from Restaurant week)?
