I hope everyone has already been to these trucks (one on 34th and Walnut, another on 36ish and Spruce), because they have revolutionized my lunch experience. The bill the menu as "whole world cuisine," meaning they've got asian, south american, italian and middle eastern-style offerings. The daily selection of hot wraps (3.50) is what I usually pick from; the Ranchero Wrap with Tex-Mex stew, brown rice and tofu is awesome. They have daily specials too; today I had the Three Layer Enchilada Pie (4), with nice grainy corn tortilla. Every other week or so there's a Louisiana Cornbread Barbeque special, with spicy tofu sausage. This is not to be missed. The only thing to stay away from is the baked tofu on rice from the regular menu, it's all congealed and dense and gross.
They have a nice selection of Natural Brew, Knudsen's and Ginseng Cola drinks too.
