Osaka Osho Kesennuma

No specific recommendation. Everything is here !

Yes, we have it

Maybe. But I recommend Den-Den Town If you want to buy anime stuff. There are many shops about anime cultures. It will take 20 minutes by walk from Dotonbori.

It is really difficult to find vegetarian food here (and in most of japan). If you are okay with eating fish, then you will have tons of options!

The famous one is the signboard of Glico, which is fun.

Lots of stores of all types and food is everywhere. You can buy literally anything there just got to go explore! But the main street has the most street food!

Excuse me I don't know because I'm not local. The skewers were delicious. I don't remember the store name. There are various shops so take a walk I think it's fun.

You depend on when you plan to go there. Usually at the end of the afternoon, to enjoy the entertainment and then the evening to make a good restaurant. I hope I could help you.

yes you can find location use google maps

I think okonomi-yaki is most popular.
