Any public WCs 🚽 in Dotonbori?

Hi all, yesterday was our first time in Dotonbori, and, to be honest, it wasn't a very pleasant experience)) It's understandable that it's generally foreign tourists (like us) and overpriced, but… are there any public toilets available??? We did not find any, got rejected in couple of restaurants and finally found one in an hotel. So now we wonder, if there are any public toilets available? In Seoul, for example, they are everywhere… Thanks )
