I know when I was with Schneider, the taco truck that came by the Laredo operating center was pretty dang good.
The one that comes to our terminal in Laredo is darn good. She makes a 3 pound chorizo breakfast burrito.
Food truck's are the new hot deal,I have eaten street food all over the USA and Mexico and never had a problem.
They are good. Nothing fancy just simple food cooked properly... well, maybe cilantro and onions can fix anything.
