Fish or Chicken Ramen?

I'm not a vegetarian, but I usually stay away from pork and beef, in favour of fish or chicken.

Are there places they serve non-meat ramen? I once had shark ramen at an onsen, but wonder if something like that can be found at regular ramen shops, too. Preferably around Shinjuku.

Hi!
Following 2shops are said to serve ramen of fish soup.

1.Menya Musashi
Nishishinnjuku 7-2-6, Shinjuku-ku(JR Shinjuku
sta. west exit)
2.Kamado
Kabuki-cho 2-46-7, Shinjuku-ku(Shinjuku sta.east exit)

Thank you.

I checked out "Kamado" a few days ago, and they did have fish based ramen. However, as far as I could understand, the broth was based on both fish and meat, and they still put in pork unless you specifically ask them not to.

Anyway, wasn't too bad.
