Tonkatsu by Ma Maison. Located at 333A Orchard Road, #02-35 Mandarin Gallery, Singapore 238897. Can’t decide what you want, pork loin, prawn or pork fillet.. Mameton Set under the Iroiro Katsu (Assorted Katsu) will be your best choice! It has all in 1 plate – Pork Loin, Deep Fried Prawn and Pork Fillet!! They were all well deep fried on the outside and juicy tender in the inside!! It taste even better with their sauce dip too! One of the places that served the best Tonkatsu! @tonkatsubymamaison #hungryunicornsg #tonkatsubymamaison #mamaison #tonkatsu
