This is Texas, so it's understood that there are quite a few margaritas to be had out there. And before we went on this quest we were pretty accepting of whatever 'rita goodness was served to us. Then we walked into Sol's. To be honest, we weren't thinking Best of Dallas. We were just having some Mexican food with a friend and decided to imbibe. Our patient waiter discussed with us the merits of the top shelf and urged us to choose that over the basic version. A little suspicious of a possible up-sell, we went ahead. Bless that man! Sauza Conmemorativo and Gran Marnier provided an outstanding base for what our bartender concocted for us. It was light, not too tart, not too sweet, didn't burn the hair off our chest, and yet it sure as hell hit us about 10 minutes later. This top shelf schooled us in the finely prepared margarita.
