The Place Ms. Oshige is all Drunk
The sign says “Izakaya Gudenguden.” An izakaya is a casual drinking and eating place. Gudenguden describes a person who’s really drunk, so the name of the place suits Ms. Oshige well.
The banner probably says Monja. Monja is a Kanto-local food that is cooked on an iron plate at your table (Ms. Oshige is sleeping on such a table, most of the table is the iron plate, except for the edges.)
