Ryū Sasakura creates cocktails dubbed "The Glass of the Gods" at the Eden Hall bar in Ginza; hotel redesigner Kamishima holds deep disregard for bartenders because of an embarrassing mistake he made as a younger man.

Miwa Kurushima comes to Eden Hall to ask Ryū to help find her "Menu of the Heart" due to family misfortune linked to her breaking a bottle of alcohol as a child.

Ryū uses the margarita and its history to show Shimaoka, the retiring head of an advertising agency, how love can live on even in the wake of actress Mieko Yuzuki's death.

Ryū assists a couple on their first date; Sayo Yusada is waiting for her husband for their anniversary, however the two have grown apart.

Ryū lifts the spirits of downtrodden salesman Shibata by making a daiquiri and recounting Ernest Hemingway's story "The Old Man and the Sea."

Screenwriter Shizuo Kasahara has trouble writing so he goes to various bars, orders four brands of Scottish single malt whiskey and poses a riddle to bartenders no one can solve until his director friend catches up with him and they encounter Ryū.
