El Ultimo Taco Truck moves around, but is usually planted at the intersection of Antoine and Long Point on the west side. As with any good old taco truck, it only accepts cash and you'll mostly have to place your order in Spanish. On busy days, El Ultimo has a waitress who takes orders from people standing in line and relays them to the men cooking inside. The tacos are some of the most highly regarded in the city, and the breakfast fare is especially good. El Ultimo deals in more than just your standard barbacoa and chicharron tacos, though. And you get a lot more than just a sprinkle of cilantro and raw onions on your order. Here, your tacos are topped with a handful of queso fresco that quickly melts into the hot meat, as well as a mess of caramelized onions. You'll get your chopped cilantro, to be sure, but you'll also get a few buttery hunks of avocado on top along with everything else. They're majestic tacos, towering high and requiring nothing other than a squeeze of lime juice on top.
