The very first thing Hank did when he arrived in Sacramento was look for a diner. He grew up on homemade food and friendly charms and so he found solace in a traditional American diner. So when Hank wanted to make a place for himself in the city he decided to do that by opening his own diner with a garage attached to it. A place he could work on cars and eat pie without having to rely on anyone else. A place of his very own.
The place had only been open a couple days at this point. The exterior made it clear to any who passed that this was a restaurant in the style of a 1950s diner. In effect though it almost looked like a firehouse, because right next to the diner facade, attached right to the building, was the entrance to the garage.
The interior followed that design as well. Maybe Hank was living in the past a little with the design of the building, but to him it was a little bit of nostalgia, and a little but of home thrown in to make the place feel welcoming.
Coming out of his office there were only two customers so far, so Hank asked one of his waitresses to get him a piece of pie and he took a seat at a booth he had placed specifically because of the wonderful, clear view he had of the street. He sat, ate his pie, and watched the world go by.
