We went around 5:30pm-ish on a Sunday evening.
The line up was quite long. One staff member with a clipboard will come around, and ask if you got a number or not. If they didn't get you in the first round, wait a bit. They'll be back for you!
I noticed the island seats have hooks under the table, to hang jackets or bags.
We sat down around 6:15pm. The place was packed! I had ordered the Special Tonkotsu Ramen (Shoyu) and it was delicious!!! The soup base was creamy and I liked it. The soup was a little salty but hey I still enjoyed it!
The service was good, the staff went around with water refills!
