I doubt Austin deserves credit for starting a trend. I read more than 4 years ago an article in the LA Times about taco trucks there, some of which sounded pretty upscale compared to what I knew of in Houston.
Roadfood.com has done several features on NYC trucks, including one recently on The Treats Truck, which dispenses gourmet desserts.
Anyway, what about Houston? Do Tacambaro, El Ultimo, Jarro count as gourmet? What else is there. Anything over there on the streets in the Galleria???, Memorial??? I mostly look for mobile vendors in poorer, working class and ethnic neighborhoods; maybe I'm doing it wrong.
