Yamatoya Honten is located near Dotombori street which in addition to being open 24 hours allows you to enjoy the night life. I came to Osaka to attend a concert and they were kind enough to allow me to send my tickets which allowed me to attend the concert.I had a feeling I would be back late, but it wasn't an issue as they are open 24 hours and I didn't have to worry about being locked outside or being a nuisance by coming back after hours.
