The exterior already had a modern yet mood-filled presence, and once inside, the clean aroma of specialty coffee welcomed us so nicely. It was not overly bustling, but calm and stylish—just the right space for a Sha-ro-su-gil date or a long chat. ![Calm interior at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-04-19ouo-900.webp) ![Stylish café space at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-05-195i3-900.webp) ![Interior atmosphere at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-06-19vf0-900.webp) ![Café interior at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-07-jsnvo-900.webp) ## Our handmade dessert and coffee order After settling in, we looked over the menu at the counter, and the handmade desserts arranged in the display case looked seriously amazing. The crumble pies and muffins especially caught my eye right away. - Iced Americano - Iced long black - Yellow cheese muffin - Handmade crumble pie We decisively picked two clean, dessert-friendly drinks and two signature handmade desserts. Even the neatly arranged presentation was already bursting with Instagram-worthy vibes. ## How the crumble pie and yellow cheese muffin tasted We sat down straight away and got into the coffee and desserts. ![Ordered coffee and handmade desserts](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-08-bldsg-900.webp) ![Long black, Americano, and handmade desserts](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-09-1pc0i-900.webp) ![Handmade crumble pie and yellow cheese muffin](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-10-mcjkh-900.webp) ![Coffee and dessert plating](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-11-uv8va-900.webp) ![Drinks and desserts ordered at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-12-16oa2-900.webp) ![Handmade desserts and iced coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-13-1q595-900.webp) ![Crumble pie and coffee pairing](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-14-1m3ec-900.webp) ![Dessert menu on a café table](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-15-1lbvr-900.webp) ![Coffee and desserts at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-16-r23ri-900.webp) ### Handmade crumble pie True to its status as the undisputed signature here, it was crisp on the outside and moist and pleasantly chewy within. With every bite, the crumble’s nutty, sweet flavor filled my mouth. It was not overly sweet, and the ingredients’ natural flavor came through, making it dangerously moreish with coffee. I immediately understood why people call this a Sha-ro-su-gil handmade pie favorite. ![Handmade crumble pie](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-17-tz5ol-900.webp) ![Crumble pie and coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-18-1b45j-900.webp) ### Yellow cheese muffin This muffin stood out for the sweet-and-salty appeal of its dense yellow cheese. One bite brought a deep cheese aroma along with a rich, moist texture. Anyone who loves cheese would enjoy this quality without hesitation. ![Yellow cheese muffin](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-19-14k77-900.webp) ## The iced long black and Americano pairing For reference, a long black uses less water than a regular Americano and is made by drawing the espresso first, giving it a deeper flavor and an appealing weightier body. A sip of the long black showed a nutty, full-bodied character that made the sweetest balance with the crumble pie. The clean, refreshing iced Americano also cut right through the richness of the yellow cheese muffin, leaving my palate refreshed. The beans’ own flavor was so excellent. ![Iced long black and dessert](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-20-dhl8g-900.webp) ![Iced Americano and yellow cheese muffin](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-21-qabvk-900.webp) ![Coffee and handmade desserts on the table](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-22-1ru1v-900.webp) ![Desserts and drinks at Pulse Line Coffee](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-23-1kg6f-900.webp) ![Coffee and desserts at a Sha-ro-su-gil café](https://img.superchart.com/images/sharosu-gil-hwangcheese-muffin-coffee/sharosu-gil-hwangcheese-muffin-coffee-24-1mg1a-900.webp) ## Final thoughts From the polished atmosphere to the quality desserts and coffee alive with a deep bean aroma, this was a perfect hot spot on Sha-ro-su-gil.
