Yogurt and her dad are out for dinner. I guess that means they couldn’t catch any fish to eat.
As this is Yogurt’s first time at this particular restaurant, she takes her time to pick out her dinner. Yogurt’s dad already knows what dish he wants, that he didn’t even have to look at the menu. Being a chef himself, maybe it was his expertise that aided him. Or perhaps he’s just been to that restaurant before.
At least in my experience, there’s always that one person in your party that knows exactly what dish they want, leaving you straggling for a menu item to choose.
