Sharosu-gil café for Guatemala filter coffee: Pulse Line Coffee

In short

Pulse Line Coffee is a new black-toned café in Gwanak, Seoul, one block up from the main Sharosu-gil street near Seoul National University station. On a weekend morning our writer went alone and ordered filter coffee (bean of the month), a rhein sponer (cream-topped coffee) and a handmade crème brûlée pie, with the month's bean a Guatemala tasting of dark chocolate and walnut. Pulse Line Coffee is a good pick if you want to choose between several filter coffees, but outlets are scarce, so charge your laptop before you go.

Pulse Line Coffee's signature coffee and dessert spread

Hi, it's Sun☀ I love spending a weekend morning over a cup of coffee, and while browsing café recommendations near Seoul National University station, I discovered Pulse Line Coffee, a new spot in Sharosu-gil. I heard they had a wide range of beans, so as a coffee lover, I headed over that very weekend!

Where is Pulse Line Coffee, and how far is it from Seoul National University station?

Pulse Line Coffee is about one block up from the main Sharosu-gil street. It's an easy walk from Seoul National University station too. Being slightly off the main alley, it felt much quieter.

Inside Pulse Line Coffee: pulse motifs and a black-toned interior

Once inside, pulse shapes representing a heartbeat pop up everywhere — on the cups and plates, on posters, even in the design drawn on top of the einspänner. It's all unified around the pulse motif, which felt like a nice match for the café's name.

Black-toned interior with pulse-motif decor pieces

Overall the interior is black-toned with red accents, which made it feel clean but still full of atmosphere. There are plenty of cute little cafés in Sharosu-gil already, so it's nice to see a café with this kind of black mood too.

The café also has a membership program, which looked handy for people who work nearby or visit often to rack up points.

Pulse Line Coffee's drink menu board and counter

I'm curious about the ba-re-yo (vanilla lemon yogurt) and mulberry yogurt, so I'm planning to go back. The menu is varied, so I'd recommend it as a café near Seoul National University station.

How many filter coffees does Pulse Line Coffee pour?

Seating with 2–4 person tables at Pulse Line Coffee

Seating is mostly 2–4 person tables, and the chairs were comfortable too. Being a weekend morning, there were families as well as people just stopping by for a relaxed cup of coffee. Seeing decent crowds even at a brand-new café made me weirdly proud, like I'd found a good spot hahaha.

What we ordered: rhein sponer, filter coffee and handmade crème brûlée pie

Since it was my first visit, I figured I should start with the signature menu, so I went with the signature line.

Filter coffee, bean of the month: Guatemala

The filter coffee had several bean options, and without asking what the month's bean was, I just picked one like a random draw. Turns out it was the Guatemala bean, with a heavy body and notes of dark chocolate and walnut. I usually prefer coffee with acidity, but this dark cup, which I hadn't had in a while, paired really well with dessert.

Rhein sponer (cream-topped coffee)

The rhein sponer had a creamy texture that would satisfy anyone who loves an einspänner. The cream on top was thick and smooth, blending nicely with the coffee. Sugar rush and caffeine boost in one go!!

The handmade brûlée pie had a texture like cookie dough with a touch of tanginess, and the brûlée top made it great to eat alongside coffee. It wasn't heavy, so it was good for a light bite!!
