Tragic that people saying this place is expensive. You probably make $60000 a year and whinge over $2.50 coffee. Or you are a backpacker trying to scrounge out $12000 over 6 months. Honestly, get a grip on reality.
I have travelled to Indo for almost three decades and this coffee is as good as anything I have had tried. The staff are lovely and the service is very efficient. They even open early for the caffeine mob after a hit before diving.
If this place doesn’t work for you buy a jar of Nescafé and add hot water in your hostel.
