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. Embarking on her mission to infuse Asian and European flavors with her original and distinctive concepts, Chef Mandy will evolve seasonal menu presentations across ATAS’ culinary presentations.

The foundation of Chef Mandy’s cuisine philosophy lies in her imaginative style enriched by her love for discovering the alchemy of flavors and ingredients.

Rooted in the philosophy of modern Euro-Asian cuisine, Chef Mandy will evolve the ATAS journey, bringing more storytelling and experiential elements to the guests’ experience.
