Tonkatsu by Ma Maison. Located at 333A Orchard Road, #02-35 Mandarin Gallery, Singapore 238897. Rosu Katsu Set (Deep Fried Pork Loin) ! We choose Pork Loin over Pork Fillet because Pork Loin has some fats in it, thus more juicy and tender compared to fillet which is more tough and dry.. the Pork Loin was also recommended by the staff and truly, our Tonkatsu craving was satisfied! @tonkatsubymamaison #hungryunicornsg #tonkatsubymamaison #mamaison #tonkatsu
