You'll love it all.... Soju is my favorite. Be sure to ask him if he has Makoli (Mah-Koh-Lee) as well. Sake is good and plum wine is decent (just not my thing, usually). If you want to be different, inquire about Awamori as well (it's an Okinawan version of Sake.... but different enough to warrent distinction.)
I'd go if I weren't in MI and attending an DE Cigar Tasting here in Detroit.
Love them oriantal liquors....
