So after almost everyone left the boss was randomly like "lol lets get drunk 8D!" and made the chef serve us some warm red sake. The customers get white sake, so I didn't know what kind of wine it was until she told me.
Well, I want to be a "stay in control" person for personal reasons, so I got a small bowl to taste a bit (the others had big ones o_o; like, big soup bowls) It's actually quite sweet, I barely tasted the alcohol... good, but not very fond of the flavor when I was about to finish it.
