What would convince Ron Swanson to try ethnic food? Maybe this meat tornado in Leo's Taco Truck in Los Angeles. It didn't literally kill a guy last year (as far as I know), but it does offer top-tier Mexican food.
The truck serves tacos al pastor, which is a type of vertical roasting. Serious Eats describes it:
There, in true al pastor form, the taqueras marinate thin, thin slices of pork shoulder in a mixture of chilies and aromatics colored bright red with achiote. The slices are then stacked onto a vertical skewer, forming a large, bell-shaped trompo (spinning top), which gets topped with an onion and pineapple, and slowly rotates in front of a vertical grill.
