USBG Milagro Margarita Competition Tequila may come from south of the border but those who will put it to good use are from all over the world. Join us for the United States Bartenders Guild Milagro Tequila Competition as twenty-eight bartenders from 14 different cities will put their best margaritas up against one another. You'll be able to sample the festive spirits as the bartenders compete not just for personal fame but the right to bring the title back to their hometown.
