Yes, it's ramen soup. No, it's not like the 20/$1 stuff you get at the grocery. If you've never tried restaurant ramen, especially Hakata ramen - you MUST. It's a creamy and very flavorful pork based broth with firm yet chewy ramen noodles and it's just irresistible! I could literally eat it until I exploded.
And 5 minutes later it's gone. :)
They also have other goodies, like a Yakitori menu and things like dumplings and the best fried rice you've ever had!
And ICEFREAKINCOLD beer.
Shin-Sen-Gumi is located on Brookhurst and Yorktown(ish) in fountain Valley. Be prepared to wait for a seat in this very small yet very popular hangout.
