I've been to the food cart a handful of times. Food is always quality and you get a good mix of textures and flavors in the pita sandwiches - crunchy salad and chips, smooth hummas, soft-on-the-inside-crunchy-on-the-outside falafel (or tender chicken or both), and some nice acidity via the pickles. It's really everything you could ask for in a quick filling lunch sandwich. The only downside is that it doesn't magically appear whenever I need to fill my belly during the day.
