At this fourth annual event, bartenders from 32 restaurants compete for bragging rights to the best margarita in Dallas. From 5 pm-10 pm, attendees can sample the margaritas (pace yourself!) and vote for their favorites via text message. The winner walks away with a $1,000 cash prize, and the event benefits La Voz del Anciano (The Voice of the Elderly), a local nonprofit that helps serve the needs of the elderly Latino population.
