Here is the website link: http://www.pablo3.com/. It looks like cheesecake but also a pie. Taste wise, I found it has stronger custard taste than cheese. More like pudding instead. Overall, it has good combination of both. If you are starved, you might be able to eat the whole piece alone.
I bought it at Umeda Station in Osaka. The queue wasn't too long.
It was chilling and raining day. They provided the "raincoat" for our take-away paper bag. Very service-oriented right?
The center was soft and so yummy! This was the dinner we had on our second day in Osaka.
