One of the stalls at Pasar Bella (Suntec) is Grillo, which I've patronised several times for the donburi. My fave is this one - Japanese rice topped with beef slices, an onsen egg and fried garlic chips, and drizzled with a sweet, truffley soy sauce. I thought the garlic and truffle went really well together, and the beef was a tender and juicy medium. Will recommend it!
