Katsudon Chiyomatsu Dotonbori Main Store is a katsudon restaurant in Dotonbori, Osaka. The pork cutlets are aged for 24 hours and come in 2.5 cm or 5 cm thicknesses, with options to dip them in yuzu salt or curry salt. The shop seats 12 people at a counter only and takes cash only; a weekday visit at 2 p.m. involved a 30-minute wait. The 5 cm cutlet can be dry in the center or cold inside.
