This coffee shop is in Gangnam, and only minutes away from Gangnam station, but worlds away from the mansions on coffee hill like Alver:

It is very small with just a few seats and a basic menu. For hand drip, the menu was short but totally sufficient:
I went for the Yirgacheffe. Process-wise everything was pretty basic. No scales or timers, and instead of via a carafe, the coffee was dripped straight into a cup (which can be fine in my opinion). Also, the dripping was less dripping and more steeping – keeping the water level pretty high at all times.
The result was nothing extraordinary, but I guess its value for money: The prices are half of the close-by competitors. But Kaiser Coffee has not made it to my list of favorites.
