snake?
You might have had Unagi (eel) in Japan.
It looks weird but you'll like it once you taste:)
Then, how about Dojo(loach)?
It also looks like a snake↓↓
My friend ate this Dojo nabe (dojo pan).
I had this Yanagawa nabe. (loach and egg-boiled-in-pan dish).
At first, I thought it would be smelled fishy but it didn't at all.
Also, not so expensive as Unagi, you should try it when you come;)
Actually, it is one of a local dish here.
