Osaka Castle. The original one was burnt down. We enjoyed the walk around the palace grounds and there are lots of push carts selling street snacks. Japanese walking their dogs, jogging.
Access via Morinomiya station. Another short walk to about 15 mins.
The chicken fat of the yakitori simply melts in your mouth together with bbq spring onion. Beef liver was still tender in the centre. But I opted out of the chicken wish bone yakitori which is a local delicacy.
