The location of this establishment is quite unique, in the highest flood of a traditional market in South Jakarta (Pasar Santa). I strongly suggest to check out their Instagram account (@abcd_coffee) before decide to try a cup of coffee here since the opening times is a bit random. Although in general they are open in weekend in the afternoon. The coffee is great, the service is excellent. They're always provide chance to chit chat with the customer waiting for the coffee. The baristas also top notch, some of them are regulary being a judge for international/national level barista competition. How about the coffee? Excellent. The beans is selected, other than fine local beans, they also import or received a premium beans from their colleagues.
What makes it different is that they rarely give a price tag for their coffee, what we find is red appreciation jar, where people expected to pay what they think reasonable for the coffee that they got. They also have barista class, where portion of the course fee are allocated for free seats for SOS Children's Villages. A very nice sociopreneur approach. Sometimes they also held charity brew, inviting world class barista with world class coffee bean, and donate all the money collected to social cause.
