The saga of Patty's Taco Truck and the Upper East Side

We have often spoken of the city's relatively new foodie phenomenon -its food trucks. However it seems that the residents of the Upper East Side are not too happy about Patty's Taco Truck which has been serving out reasonably priced and delicious tacos from their spot on 86th and Lex. I haven't eaten at this particular food truck but have eaten at other around the city. Do you think food trucks add to the city or are a nuisance which are hampering other legitimate businesses in the city? I am a great lover of street foods so I don't mind the trucks but it seems that many in NYC do if you read the comments in response to the article. What do you think?
