Dined here during a full restaurant though barely any wait. Ordered the mango sago and the red bean with coconut milk.
Tons of menu options make ordering complicated, best to stick with the fan favourites. Mango sago had good explosive mango flavour. Not a surprise, exactly what you'd imagine it to taste. The red bean coconut was nothing special. Mix soft red bean and add coconut milk at home and viola.
Not a place for exceptional service, just expect to be seated (read: seat yourself), order, dine, pay, leave. All with little or no interaction from waiting staff.
From my experience, Double Ming is somewhere I would only visit if I had a serious craving for mango but next time around I see myself ordering the rice balls with peanuts. Would definitely give the menu another chance.
