I finally made it back to Kurohanabi tonight to get their gyumotsu, and it was awesome. That rich, savory, and slightly spicy broth was exactly what I needed to line my belly with tonight.
This gyumotsu shop from Hokkaido opened an outlet on the former grounds of Fugetsu at Suntec's Eat At Seven (3 Temasek Boulevard #03-316, 6250-1561).
