You must get the pork jowl/cheek. I think it really made our meal. Just melt in your mouth, perfectly slow cooked/braised, awesome delicious-ness. My bf had the shio (salt) ramen and I had the kara-miso (spicy miso). Both were really good. Basics come with bamboo, chives, mushroom, and cha sui. We added the soft boiled egg.
Compared to the other major ramen places. I think santouka has the best meat (pork jowl). The broth is also pretty good.
I guess they don't have as much variety of noodles or richness of broth (the broth here is quite rich and salty.. So it's not for everyone). They seem to have a larger menu than other ramen places...With rices and salad dishes (didn't try these).
Service was good (as the restaurant was at 80% capacity on a Sunday afternoon). Seating was a bit crammed but that the whole ambience !
