 Agree but will play devil's advocate as this is something that always puzzled me.
Is the servers job harder at a more expensive restaurant than a TGI Friday's or Denny's?  The food is much cheaper at those sorts of places (which I don't frequent anyway, but for the sake of the argument) but are they working any less hard?
Anyway, I agree you tip on pre-discount but you also tip on pre-tax.  Those pretty much net out in this case.
While we are at it, what is the proper ettiquite for tipping on booze with dinner?  Standard at a pub is generally a buck a drink.  Now a bit different when you are talking about a $250 bottle of wine.  I mean, it's no different than opening a $50 bottle of wine.  I have heard different rules for this.  Wonder what everyone's thoughts are?
