Designing the physical layout and every other aspect that has something to do with advertising the shop turned out to be a piece of cake since I already have a vivid picture in mind.
I just applied some tweaks on how fast food restaurants used to look like in my previous world and modified them in accordance to the target market's lifestyles. The thing about quick service restaurants is that they appear accommodating to any social class.
Whether the customer is a noble or a commoner - the store aims to give the same type of excellent service. That's why in some sense, it also promotes equality among the people here.
Fortunately, the place that Ruben and I were able to afford to buy was located in a crowded district in Aria. It's a two-story building and has a decent view of the city.
