Hotel Cross Osaka by Nanba had a fantastic breakfast, lots of fine dishes even if some were more lunch-like:

While schedule-wise, it made more sense to go to the aquarium at the end of the day (fewer people, later closing time), but it made more sense for us to start with the aquarium. There was indeed a longish line, but by skipping some scheduled shows, we got ahead of most of the heavy crowd for some more quiet viewing:

cool to see through the mouth :)

I didn't ask how much this one costs :)

Next, we went to the Osaka Science Museum. Virtually no English, but very nice exhibits (click to see that museum)

We went to the nearby art museum, and honestly the expo wasn't that great:

My dad then went out shopping, and I went to check out Den Den Town, the supposed Osaka Akihabara. It had a few similarities, but it wasn't quite on par. I went to check out some game rooms though :)

this machine has a rotating control to thrown coins in the right place

I was more troubled by those games being played by kids maybe not even old to be teenagers

Osaka did have its own branch of super potato, selling old vintage computers

Super famicon, anyone?

Oldr Sega Mega Drive?

Obsenely overpriced vintage LCD games

bling!

It's always fun to see Japanese people playing games. That lady dancing was pretty good:

Next, I went back to Ame Mura and went to check out a couple of Neko cafes. The first one had very unusual cats :)

And it was then time to go back to meet my dad for dinner in our hotel restaurant:
