One of a must visit is this museum, you pay Y300 for the entrance but you get a miniature bottle of sake as souvenir! I never know how they making the sake, so is very interesting for me understand how it work. In the picture is one of the old sake bottle and cup set.
On the way walking back from Dotonbori to Namba Private House, we passing by a shop selling this, the left side is something make from eggs and soft nice. Right side is some kind of layers crispy biscuit with middle some tasty cream! Idid not write down the shop name and all are in Japanese, so if you any chance crossing the GPS near this region, try it!
