One of my favorite places in Osaka is this restuarant/umeshu bar: PLUM
PLUM Web Site PLUM Top
They have umeshu from all over Japan, the menu was like 4 pages long...and everything from brandy-infused umeshu to green tea-infused umeshu.
I like Shoya, but that's the Bud Lite of umeshu. It's worth splurging once in a while for something even better...
