I decided to give this place another chance after it was recommended by a personal friend, whom said that their V60 filter coffee was quite good. And honestly, while I thought the Ethiopian Chelchele tasted a bit sour, it was quite flavourful and I could taste the floral notes. Beats Starbucks&Co. for sure.
And for 12₺, I think it's the best bang for your buck, since one pot of coffee equals almost exactly 2 cups of coffee, and for 6₺ per cup, I think the price is very reasonable.
Also I learned a couple of new things, apparently you can buy the coffee beans, they cost 35₺ for 250g, and also the equipment to go along with it. All things considered, I decided to bump up this place by a star and I would recommend this place for their filter coffee. It's not the best coffee I had in Istanbul, and I wouldn't come here just for the coffee, but if you're in the neighborhood, feel free to swing by.
P.S: If you want to know more about the place, here is a video about them. They're featured around the 8:25 mark.
