Recently made a visit to Shoku after seeing Tetsuro's update review and getting ROTD, I felt that it would be justice to give it another go.
On the second visit there was DRASTIC improvement in everything, except service because that is as good as it gets.
Had to try the Buta-san again and definitely there was a change in depth of the broth, a savory pork flavor with an almost smokey finish. The consistency of the broth is still a bit thin but that is all personal preference! The noodles that were a bit of a downfall for me last time have been replaced by a thicker noodle that gives it the satisfying bite, mmm!
Also tried the specialty XO Tan Tan Men, which had a prominent seafood taste with a very forward nutty sesame taste. The ground pork had a clean fresh ginger finish which worked really well for me to combat the savory broth. I'm not sure about its adherence to traditional Tan Tan Men, but it is definitely worth a try in your ramen rotation. My only complaint was there there was not enough bok choy and it being an expensive ramen @ $11.
I can say confidently that it is a great addition to my ramen rotation, however also the more expensive one than the rest.
