M8 by Marini's
Time Out says
M8 is a separate bar next to Marini’s On 57’s new steakhouse, Marble 8. Yes, it may not command as much attention as the bustling Marble 8 but this bar with an indoor lounge and a garden terrace onlooking the KLCC park doesn’t feel like an afterthought. We absolutely love the Mora Anatomy cocktail.
