The article covers this. Wheat noodles and a rich broth were new.
> I think the best Ramen I've had was either down the end of the toden line or out Shinjuku
Menya Musashi and Fuunji are both generally very well regarded and about a 5-7 minute walk from the SW part of Shinjuku station.
Interesting how many of the types listed at https://en.wikipedia.org/wiki/Japanese_noodles are at least partially wheat based (62.5%). It perhaps follows that prewar Japanese cuisine was substantially less varied and more regionally defined.
Annoyingly some other americans next to us at Fu unji were complaining about the pork in the ramen.
My favorite of that trip was actually the Kio chain in Osaka (cold noodles and beer on a warm summer day were perfect). There are a ton of great resources for sussing out good ramen in Japan, thankfully.
What noticed though was that while all the ramen I tried was better than what I've had stateside, each ramen shop would typically nail one or two things and the rest would be good but not amazing. I never did find an egg as well cooked as I have in the Bay Area.
Also right by Shinjuku, the French bakery was pretty darn good.
