Let me just start this by saying, DON'T BUY INTO THE HYPE.
First off, their gyoza tastes like just a chinese dumpling. DON'T GET IT, WASN'T WORTH IT. Got a bowl of tonkotsu and tonkotsu black which both were kind of disappointing. THE BLACK GARLIC OIL TASTES LIKE IF I COOKED A STEAK AND POURED THE LEFT OVER OIL INTO MY RAMEN. The pork was firm yet chewy but the egg was cooked perfectly. On top of it all, it was super salty and the portions are smaller in comparison to most ramen places.
The service is nice and they're quick but the actual waiting time is 30 mins or so.
I would have rather gone to ajisen ramen.
