花よりだんご

Sweets are preferred to flowers.　(means the practical is preferred over the aesthetic)
It originated from the day of "flower viewing" 花見. Japanese traditionally travel to the countryside or visit parks to appreciate the beauty of nature. （I think now it is the right season. 桜の季節）Yet human nature being what it is, people seem to show more interest in the food than in the flowers.

いやだわ、あきちゃんたらせっかくお花見に来たのに、食べてばかりいて。

昭雄、お前やっぱりはなよりだんごのﾀｲﾌﾟだな。
