From a UpRoxx.com online article:

 The Crack Shack … offer(s) genuinely tasty chicken sandwiches with meat sourced from farms outside of the industrial farming world. They… cost roughly ten times as much as a McChicken and more than double the Popeye’s Chicken Sandwich.

“Solid, good cooking and comfort are always on-trend,” says Chef Richard Blais. We reached out to the Top Chef all-star and co-owner of The Crack Shack to talk chicken sandwiches because, well, that’s all people seem to be talking about lately. We figured, if anyone would understand how a sandwich basically turned into a cult obsession at the tail end of summer ’19, he might.

“Chicken is incredibly universal and always a crowd-pleaser,” Blais adds. “As is fried food, so… I think it’s just math.”

The cushy bread, the tangy mayo, the crunch of a salty pickle, and, of course, a beautifully seasoned and deep-fried piece of chicken (hopefully brined thigh meat) is about as complex-yet-simple as a sandwich can be. Add a little heat and it’s bliss in a bun.
