We came here on a Monday evening, and had to wait about 20 minutes for seats for two. This restaurant is quite popular/busy, so they'll likely ask if you're okay with bar seats or sharing a table with others.
We both ordered the white sesame shio ramen, which we enjoyed, but I think I prefer Hokkaido Ramen Santouka and Sansotei a bit more. The gyoza was also good!
