i'll start with the business license! just putting my threads here not to keep track, but as we were speaking earlier, this is a joint regain for lupin, the bar from bungo stray dogs where dazai drank his sorrows away during his mafia time.

as per canon description, this is it:

The bar is in the basement, hence, there are no windows. As quiet as a bear cave, the bar is well stocked - the counter, seats, walls lined with rows and rows of empty bottles, taciturn regulars, and the bartender in his red vest.

Because so many things have been squeezed into this tight underground space, the walking space only allows for two people to squeeze past one another. The items in the shop have witnessed the passage of time, giving guests the feeling of being suspended in their time.

pictures as follow! yes, it is a real place! one, two, three, four.
