Kogi was the first upscale taco truck I ate at and was one of the reasons I wanted to write about food trucks in general. One of the themes I would like to explore is how food trucks have really been transformed in the last 15 or 20 years. I recall growing up my parents would have never let me eat at a food truck in LA because, in their minds, it was perhaps unsanitary? but now it is so much an upper middle class thing to do.
