At the bottom of every bowl of ramen at Ichiran is a Japanese phrase [この一滴は最高の喜びです] or in romanized Japanese [kono itteki wa saigo no yorokobi desu]. Due to the thick broth, you’ll only notice this at the bottom of the bowl if your drink up (almost) every last drop. That’s actually quite apt as the translation roughly translates to “this one drop is the greatest of joys” implying that even the last drop of the broth is delicious. If I were to paraphrase, the gist of it would be: “good to the last drop”.
