As a coffee aficionado, I know Ritz Coffee is somewhere in an alley northwest of Guk-dong Station. For public transportation, coming out of Exit 2 of Guk-dong Station is the quickest way. The shop is small and cozy. The menu is divided into general and specialty options. They carry five types of specialty coffee. Just looking at the menu tells you it's a coffee shop with its own unique style, despite its small size. I asked the barista to recommend a drip coffee, and they said they'd call the owner to ask. Soon, the owner appeared from somewhere. Right away, you could tell he was a true enthusiast. He recommended the Guatemala El Vergel beans, but after looking at the bean bag, he said there wasn't enough and instead recommended Ethiopia Geisha beans. He brewed the coffee with familiar movements. I was reminded again that drip coffee heavily relies on the brewer's touch. Geisha pairs well with ice too. I was freshly reminded, through the coffee brewed by this enthusiast, that summer flavors can go so well with winter. It's all about the handiwork. When I mentioned that I couldn't achieve such a taste if I brewed it myself, they told me they even teach customers how to brew drip coffee. The thought of learning from them, whenever our schedules align, wafted up with the coffee aroma. Even when I asked the staff for the exact location, they just said it was 'somewhere in an alley in Guk-dong.' If you want to try coffee from a true aficionado, 'somewhere in an alley in Guk-dong,' it's Ritz Coffee.
