じゅんじゅん
I ran out of sake on a 2-week business trip to Asia, so I had this one at a company reception the day after I returned to Japan without worrying about my surroundings. It was great with fish.
Postscript
I ordered one cup of sake, but I was so impressed with the store's behavior that they overflowed the glass and even filled it up with more sake.
