Ray's Drive Inn - claimed origin of the puffy taco

Ray's Drive Inn, a longtime San Antonio eatery, is widely cited and advertises itself as the originator of the regional 'puffy taco,' a corn tortilla fried until puffed then filled. The restaurant's puffy tacos have been featured in national food coverage and shared widely on social media and food blogs. The chain's claim to have invented the puffy taco in San Antonio is commonly reported but has also been attributed to other local cooks, so the precise origin is debated.
