Overall, I would rate Sansotei 3.5 stars.
I had dinner here on Sunday at around 5pm. There were plenty of seats as there were only 4 other diners in the restaurant.
I ordered tonkotsu while my bf ordered tonkotsu black, both with thin noodles. The food came out fairly quick and tasted pretty much the same as the downtown location: rich, salty (in a good way), flavourful and comforting.
Normally I find ramen very rich and have a hard time finishing my bowl but I easily finished this one. I do find the portion to be on the smaller side and feel that they are skimped on the pork belly. A couple hours afterwards My bf and I were hungry again so I feel like Sansotei is a better choice for lunch than for dinner.
