I've been to most of the Sansotei locations and the service and quality is consistent.
My friend and I both ordered Tonkotsu Raman with thin noodles and a side of gyoza. The ramen came out first and was delicious as always. The egg was perfect with the runny yolk and I like how their broth isn't too rich and salty.
The gyoza took a little bit longer to come. It tastes like a typical gyoza, nothing special. It's a good side though.
The servers here are more attentive than other locations, it may be because they recently opened. They made sure our hot teas were refilled and took our finished bowls away soon after we finished eating.
Overall, good food, good company, and good service. Will definitely come again.
