If you're ever in Des Moines, treat yourself to a trip to Tasty Tacos. My sister and I stopped by their Euclid Ave. location on the northeast side of Des Moines. We went with the classic beef taco, which is folded in a soft, bread-like shell. For dessert, I ordered a cinnamon-sugar version of the soft taco shell (sorry, I can't remember its name, but it's on the dessert menu.)
By far my favorite taco joint in town. Go there. Soon.
