I am incredibly impressed. They tend to look like glass boxes,* typically with at least two outer walls of large windows. One back wall is bricked in on the kitchen side and one end wall where the bathrooms are. The front end may have glass on three sides. This is where extra seating goes.
They typically have a galley kitchen with bar seating in the middle and booths to either side that are readily served by cooks and wait staff, plus that additional seating area towards the front (towards the main road, usually).
They have sort of a bad reputation as a dive restaurant, probably in part because the building looks so much like a glorified trailer and the prices are low, but the food is good and I have always loved the chain. My dad grew up on a farm, so I come from humble people who like down to earth places like this. Reading this article makes me feel really good about being a huge fan, in spite of the classist contempt some people have for the chain.
You would think that a place that (very often) looks like a glass trailer would not be the first thing open after a hurricane. So, I am astonished, but happily so.
