Well, missed this opening by a few months also. Tried to go last night but it was closed. Even though the sign says Mon-Sun, they are closed Tuesdays. For now. That might change according to the waitress.
I tried the classic tonkotsu and the chicken broth with chicken wonton ramen with a side of pork chashu and special egg.
The tonkotsu broth I felt was easily inferior to Yamadaya's. At least one or two notches below in terms of porkiness and flavor for me.
The chicken broth was excellent. Rich and milky but different. A nice change from the ubiquitous tonkotsu broths.
Noodles I thought was a bit softer and less al dente than the ones at Yamadaya. The chashu was good. The egg was stellar. I wish all ramen places had this egg. Weird that you have to order it separately though. Chicken karaage was also good and had a strong alcohol (sake? mirin?) scent. Very different from Yamadaya's version but just as good in a different way.
As I suspected, I think I prefer the clean and pure focus of the shio and shoyu broths at Yamadaya these days. But I will definitely be back for that chicken broth ramen.
