La Argentina Rodante: Piaggio on Wheels
One note for the folks at Piaggio: while Facebook and Twitter are great media in their own right, you really need a website. It's hard to convince people to try your food when they don't know what to expect until they've chased you down. At least put up a Twitter feed and your menu.
Skirt steak tacos were quite good (with a chipotle-laced salsa that was not too thin or too overwhelmingly smoky). The chimichurri, which was the only nod to Argentina in the dish, gave what would otherwise have been a standard Mexican taco a nice herbal, garlicky zing.
I also ordered a caprese empanada, which was mozzarella, tomatoes and basil stuffed into an empanada and deep-fried. I honestly prefer my empanadas baked (as they are at El Gaucho #2 in Anaheim), but for fried empanadas, this was pretty good, especially with more chimichurri sauce spread on it.
I was too full to try the truly Argentine dishes (choripan, for example, or the chicken milanesa sandwich), the bacon hot dogs or the desserts (mmmm, alfajores), but it is nice to see something besides Mexican and Mexican-with-Seoul roaming the streets of OC. I was also intrigued by the bolinhos de peixe, Brazilian fish fritters, but they were not on the night's menu.
Now if only we could get that Buttermilk Truck down here... or my Holy Grail, an Italian truck that sells arancini, like the cart in Midtown Manhattan.
Piaggio on Wheels doesn't have a website, but you can follow them on Facebook or on Twitter.
