Some images become so seared in the collective mind, they are indelible and instantly recognizable.
Many years ago, I read that more people were familiar with the white-goateed Col. Sanders than with any other American image. Austin has its own collective images. Any of them might be contenders for most ubiquitous sight. It's rare enough for a non-chain restaurant to survive for a decade or more, but it's rarer still for such a restaurant to remain viable. City Grill has managed to do all of that and retain the same print ad image.
