Margarita Woes

I am a die hard Margarita fan and I am in a desperate search of an establishment that makes good Margaritas. I refuse to believe that I will have to find a new drink when I go out! I have been to Crooked Q's, Galileos and Slims but none of them have come close to the Classic Margarita. Does anyone out there feel my pain...please recommend a place that will quench my Margarita thirst.
