After a long day of walking, the order here was iced peppermint tea at 6,000 won, an americano at 4,800 won and the signature crumble pie at 6,500 won — the mint was fragrant without any bitterness, and the pie was crisp outside and dense inside.

## What the inside of Pulse Line Coffee looks like

Inside, Pulse Line Coffee has a chic black-and-red combination that feels sleek — great for laptop work. The quiet alley keeps noise levels low too.

"Brand Story" — We believe in a rhythm that flows within coffee. From the breath of roasting, to the temperature the water touches, to the moment the aroma blooms, the whole process connects into a single line, and along that line runs a quiet but strong pulse. That's the idea behind it, haha.

What I ordered at Pulse Line Coffee was peppermint tea (₩6,000), americano (₩4,800), and crumble pie (₩6,500). Even the napkins, water, and paper cups were neatly arranged.

I'd walked quite a bit and wanted something cool to wet my throat. So I ordered both the peppermint tea and americano iced~~

![Close-up of iced peppermint tea](https://img.superchart.com/images/pulse-line-coffee-peppermint-crumble-pie/pulse-line-coffee-peppermint-crumble-pie-21-1wwej-900.webp)

The peppermint tea, known for its refreshing scent, lifts your mood with a cool minty aroma. The clean, crisp finish leaves your mouth feeling refreshed, and it's not astringent at all, which makes it even better. The americano was also nutty without any sourness, making it easy to pair lightly with dessert.

### Signature handmade crumble pie, 6,500 won

Set on a round, stylish black plate, the yellow dessert really catches your eye. It's a handmade crumble pie topped generously with nutty, finely crumbled, crispy crumble.

Between the thick, crispy crumble is a soft, dense filling. This signature crumble pie at Pulse Line Coffee near Seoul National University Station cuts smoothly and is well worth seeking out.

Crispy outside, super dense and moist and soft inside — this crumble pie is easy to enjoy without feeling heavy. It's rich with sweetness that lingers, pairing well with a cool drink. It especially goes well with coffee for a smooth combination.

## Who is Pulse Line Coffee best for?

Pulse Line Coffee sits in a quiet spot that seems great for laptop work, and it's a simple, sleek space good for casual chats over tasty dessert. I'd recommend it as a café near Nakseongdae Station or a Sharosu-gil café near Seoul National University Station.
