So we started the morning walking around Osaka castle. The surrounding area is known as castle park and is very lively; with food stalls, street performances and the pre-workout stretches :P
After visiting Osaka castle, we headed towards the famous Dotonburi district. Honestly this place is just awesome. You can literally eat your body weight in food. We were quite overwhelmed actually.
You could come here every night of every day and still find something new. It's a must for anyone coming to Osaka.
