After eating with my sister, we were walking around Sharosu-gil and went into a café we had not seen before. It was Pulse Line Coffee (펄스라인커피), on the edge of Sharosu-gil and close to Seoul National University Station. We ordered a café latte, Pulse Milk Tea, and the crumble pie, which was introduced as a signature item.

Where is Pulse Line Coffee, and how does parking work?

The address is Unit 101, 1F, 13 Gwanak-ro 14na-gil, Gwanak-gu, Seoul. It is slightly off Sharosu-gil’s main street and also close to Seoul National University Station. When I visited, the exterior looked neat, and I liked its gray-brick finish.

The original post lists its hours as 8:00 AM to 8:00 PM, with last orders at 7:55 PM. Parking was described as using a nearby public parking lot independently.

Is the atmosphere good for sitting with friends or a date?

The black-and-red interior made me feel as though I had entered an exhibition space. The open kitchen also caught my eye, and I liked the consistent interior design overall.

Most seats were tables for two or four. They were not packed tightly together, so it seemed like a good place to stop during a date around Sharosu-gil or to have dessert with a friend after a meal.

What drinks and desserts are available besides coffee?

Besides coffee, there were tea, yogurt, and ade drinks. Desserts included muffins, pound cake, and pie, and the mulberry muffin caught my attention. We decided to have crumble pie with a café latte and Pulse Milk Tea. There was also a membership program, but the original post does not state its specific benefits or terms of use.

What did the Pulse Milk Tea and café latte taste like?

I took a sip of the Pulse Milk Tea my sister ordered. It was made with milk blended in-house and peppermint, with a smooth taste and a subtle mint aroma. It felt sweet yet refreshing, so it went well with dessert.

The café latte naturally brought together smooth milk and the rich flavor of espresso. It was not overly bitter and went down smoothly, making it a good match for the pie.

What were the taste and texture of the crumble pie like?

The crumble pie was generously topped with crumble, so the sweetness came through first. The caramel cream-cheese filling inside combined caramel’s sweet flavor with the gentle tang of cream cheese, so it did not feel too rich to me.

I liked the combination of crisp crumble and a dense yet smooth filling. We enjoyed drinks and pie after our meal, and it was a café I would think of when wanting to sit down for dessert as a pair around Sharosu-gil.
