OK, tall order here: Where is the best place on riverwalk to get a Puffy Taco after 9PM on a Friday. I'm on a cross country road trip and won't make it to SA until at least 9PM. I'm dying to try a puffy taco and would actually be willing to abandon riverwalk to do it, but if there are two about the same, I'd do the riverwalk location first. Please help! Leaving Tuesday night.
