When we say "American history," what's the first thing that comes to mind? That's right,
George Washington the frozen margarita machine! Mariano Martinez, the owner of of Mariano's Hacienda, invented the machine in 1971 and now the original is in the Smithsonian's National Museum of American History. But since you can't drink booze and annihilate humongous fajitas in a museum, we suggest you stick to Mariano's. And what better way to celebrate Cinco de Mayo this year than at the Hacienda that birthed a legend?
