Ascending The RuMa Hotel and Residences’ iconic spiral staircase leading to ATAS, the hotel’s distinctive historical and cultural elements play out on an epicurean journey. ATAS, with its name inspired by the Malay word for “upstairs,” exudes a more tongue-in-chic undertone when referring to something “upper-class”, The restaurant features a spacious open-floor plan where guests can browse and occupy the kitchen area at breakfast, before transforming into a show kitchen for a more immersive dining experience during lunch and dinner.

ATAS welcomes Chef Mandy Goh at the helm of the kitchen, bringing with her a wealth of experience from working at some of the world's top tables.
