With its entrance hidden inside Malaysian restaurant PappaMia at a River Valley shophouse, this joint set up by the Association of Bartenders and Sommeliers of Singapore (ABSS) serves as a training space for barmen in the daytime. But what you might not know is that the place also switches into full bar mode in the evening. There’s a wide range of spirits and liqueurs stocked at the comfy, laid-back joint (with a video game machine and a pool table). Cocktails—mixed by trainees—start at a mere $9 and pack a real punch (though don’t expect anything too creative: it’s just classics here).
