The robust tonkotsu broth, springy thin noodles and tender chashu easily make Santouka one of Singapore's best places for ramen. Go for the Shio (salt-based) version of the Pork Cheek (Tokusen Toroniku) Ramen, the real star being the pork cheek. Braised to perfection and served in perfect slices, it is so tender it's been compared to Toro, or fatty tuna. It is no wonder the queues are so long.
