Located on the third floor of Donki Mall Thonglor, Ma Maison is a Japanese family-style restaurant with a truly authentic atmosphere, frequented by many Japanese customers. Specializing in Japanese-Western fusion cuisine, the restaurant offers dishes like omurice with mayonnaise, hamburg steaks, and traditional Japanese favorites like tonkatsu, deep-fried prawn, and curry rice. A highlight is their homemade demi-glace sauce, meticulously simmered for over 28 days to achieve a rich, aromatic flavor that enhances several beef dishes.
