Perhaps I've missed it, but I haven't seen much discussion on the booming food cart/truck business in town. I'm currently having tacos from a truck near UWM, El Tenampa, which are really pretty good - cilantro and onion, as it should be, with double corn tortilla. Based in Waukesha, according to the side of the truck.
I've also enjoyed the crepes at Satellite Crepes (only the savory). I'm old ;-) so I haven't manage to catch the StreetPizza craze.
I was wondering what experiences and recs others had had?
