Based on the text below, apparently there is a special type of table in some Japanese restaurants made for eating Katsudon.
どうしてレストランのテーブルにデスクランプがあるんだろう。
デスクランプのあるテーブルを挟んで座るって、なんだか取調室を連想させる。カツ丼専用席だろうか。
But why would tables for eating Katsudon have a light in the middle? Why would you want to lighten up just Katuson and not other foods?
I did some online searches and can't seem to figure out what the reason for this is.
