Best Places for Margaritas in the Southwest. Do You Have a Favorite?

I had my first Golden Margarita on the River Walk in San Antonio, Texas and I was hooked on the American favorite, the frozen Margarita. My friend, Wendy, swears by the Margaritas and Margaritaville entertainment at Jimmy Buffet's place in Las Vegas. We have selected some Southwest favorites. Do you have a recommended Margarita hang-out that has also received rave reviews? E-mail us and we will consider it for our list.
