Pho Hoa' KC, SE corner of Independence & Paseo, behind the hooker motel
Hamburguesa Loca (thanks Jack), SW corner of Independence & Benton, across from KFC
And of course The Humdinger, on 9th, 1 block west of Prospect
Just about any of the taco trucks are good, although I do not care for the one at Independence & Benton, in the Rent-A-Center parking lot. My favorite is the one all the way down by Independence & Hardesty, on the south side of the road, beside the auto repair garage that's just before McDonald's. Not only do I think they have the best tacos, but they only charge $1.50ea for them while the other trucks are all charging $2ea.
