Located downtown, this is mostly a local diner, but probably has become more noticed since Adam Richman from Man vs. Food went there. I was a student at UTSA downtown and it fed us hungry students with their GIGANTIC cinnamon rolls and more than Texas sized portions of Chicken Fried steak.
These are in front of North Star Mall, I used to drive past these all the time when I lived in SA. They are quite prominent, but I never thought they were the *World's* largest. I never thought more about it than as a visual marker for North Star Mall.
