Ramen is not an expensive food.

Negi Ramen

Here in the US, we often spend $10+ for a bowl of ramen. Plus tip and tax makes it $12 ~ $14. Of cause you can find some expensive ramen in Japan, but ramen in general are considered cheap and fast.

Some of the places I go, a bowl of Ramen starts 350 yen ... many places sell their base ramen for 500 yen.
