My favourite ramen place in downtown. A bit of a wait for seats (~25 minutes on a Friday around 7) but well worth it. There is little waiting room indoors so if it's super busy, you'll have to line up outside.
The seating is pretty crowded so I wouldn't recommend it for big group gatherings.
I like the classic ramen the best - but ask for less salt if you have a lighter palette.
Santouka has never disappointed me - the ramen is always so flavourful and perfect for a cold winter night.
