The best Margarita in Phoenix according to the Phoenix New Times is the Margarita Especial from Sierra Bonita Rest. Ok, so they are not talking about best tasting. I can tell you that you can add all the extra limes you want to but that baby isn't going to mellow out. It is in no way the best tasting margarita but it is by far the most potent I've ever had. It is not to be trifled with, it will give you the text book two to the chest and one to the head if you are not on guard. Stay salty.
