I don't quite understand the meaning of maintaining the store ...
As the upstairs said, the most important restaurant staff is clean and courteous, and they should be discerning.
It's best to have side dishes before meals (many stores don't provide them, and I'm very resentful)
Don't use disposable silver or stainless steel tableware.
Instead, ask for shochu and rice wine.
Just set up an area where you can sit cross-legged.
ah, this is what I thought of.
