Coffee Lab in Hongdae. 

This coffee shop’s quite nice, the design is really cool. There’s chairs attached on the ceiling, the mood is kind of romantic. It’s kind of dark, with candles on each table. The price is reasonable, actually it’s a little cheaper than the regular coffee chains.

There’s a Coffee Lab Express on one of the big streets of Hongdae, but this one is a little off to the side. It’s right across the Coffee Prince cafe.
