Cafรฉ Cosmos Manual
Menu and store information for Cafรฉ Cosmos.
Intro
It is early April, and the first hints of spring are in the air as you walk through a certain residential area.
The wind blows through, making for a pleasant afternoon. In the middle of this neighborhood, you spot a solitary coffee shop.
Cafรฉ Cosmos โโโโโโ The name is written modestly above the entrance.
You think about dropping in on a whim. The bell attached to the door jingles as it opens.
The inside of the shop is quiet, with jazz playing faintly in the background. It feels cool inside, perhaps thanks to the shade, the breeze, and the brick construction.
There are a few customers you could count on one hand, but they are all focused on their coffee, books, or food. A man behind the counter immediately to the left looks up while brewing coffee.
...Ah, welcome. Please, take any seat you like. He gives a soft, gentle smile.
