Even if these trucks were parked and shot below 23rd street, many others are all over the city. They all have distinct schedule week day versus week-end. You'll find them in various locations, that can change during the day, they are all moving around and coming back. As a pop-up breakfast or pop-up lunch, they are now part of the street scene. A business that has free rent can make lunch more affordable for the customer. The in-and-out factor is attractive when your time is limited. but affordable, convientent and good sometimes means long lines, and not necssarily faster. Students, workers, visitors and even well groomed business men are in the mix. Are trucks competing with restaurants? No I don't think so, but they are competing with fast food. The trucks give the city a good view of what consumer like in a very colorful way, that stands out in front of the bland buildings. I have not yet seen the pitt-master pork truck, but I'm sure one is on is way soon.
