My girlfriend and I are going to be in Manhattan for a couple of days in January. She's not particularly chowhoundish...perhaps falling somewhere on the disinterested side of foodiedom. However, she is somewhat eccentric and has developed a mild obssesion with mobile salad carts/trucks which she claims exist in Manhattan. What I'm imagining is something like a chip-wagon that would sell salads on the street to take-away. Now I've spent a little bit of time in New York in the past few years and I've never seen one of these things, even in the summer. (But mobile salad isn't exactly the biggest blip on my gastronomic radar!) Does anyone know if these places exist and if by any chance they'd be open in January.
