Luckily a spot opened up next to the air conditioner, right by a light fixture, so we got to sit and rest 👍 ![Table by the window with a light fixture](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-07-cdyad-900.webp) ![Calmly lit café interior seating area](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-08-hp61c-900.webp) The inside has a quiet, calm mood but it's not bad for talking — before I knew it, time had flown by chatting with my friend 😆 ![Detail of the café's interior decor](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-09-1r0pn-900.webp) ![Decorated order counter at the café](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-10-dauz0-900.webp) 🔼🔼 Even the order counter is decorated with such style that I kept staring at it haha ![Decor pieces near the Nerdy Blue Burrow counter](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-11-6wvei-900.webp) ![Coffee-related decorations beside the order counter](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-12-h1xzi-900.webp) ## Nerdy Blue Burrow menu: cold brew, hand-drip and dessert sets Wangsimni café Nerdy Blue Burrow specializes in cold brew and hand-drip coffee, but they also have other menu items (non-coffee, alcohol), so check the menu board ^^ ![Menu board listing cold brew and hand-drip coffee](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-13-1ergl-900.webp) And there are dessert sets to enjoy with coffee too — fresh cheesecake, hazelnut chocolate pudding, banana pudding, and classic financier 💕 ![Menu board with desserts and set menus](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-14-1n5h1-900.webp) ![Vertical photo of the menu board showing dessert set info](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-15-8ri56-900.webp) We ordered Nerdy Blue Burrow's signature set, the Cheating Plate. > The Cheating Plate — "Diet starts tomorrow. Today, we escape." ![Cheating Plate set with two cold brews and assorted desserts](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-16-17tzj-900.webp) The Cheating Plate is a dessert set with two cold brews paired with fresh cheesecake, banana pudding (scoop), and classic financier, all served with house-baked granola — "in the end, it was such a delicious and satisfying set 💕" ## Decaf cold brew (+900 won) when evening coffee feels like too much Sometimes you want coffee in the evening but the caffeine makes you hesitate — at Nerdy Blue Burrow you can choose decaf (+₩900), so I picked it without a second thought! ![A glass of decaf iced cold brew](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-17-bhuh8-m-900.webp) Honestly, it was evening, but also I often get heart palpitations from regular cold brew, so having a decaf option was such a relief ^^ > My first cold brew in a while. The decaf iced cold brew had a notably clean finish and almost no bitterness — smooth, balanced iced coffee :) Next time I want to try the cold brew latte too ^^ ![Close-up of iced cold brew on the table](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-18-18mwz-900.webp) ## How do the three Cheating Plate desserts taste? Next up, the desserts! A single plate combining fresh cheesecake, banana pudding, classic financier, and house-baked granola — it looked gorgeous too! ![Dessert plate with cheesecake, banana pudding, financier, and granola](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-19-autyv-900.webp) ### Fresh cheesecake The one I was most curious about was the fresh cheesecake, and one bite in, I was surprised by how soft it was haha > The deep flavor of Basque cheesecake combined with the creamy cheese cream — a taste that makes you give an instant thumbs-up! ### Banana pudding and house-baked granola Next was the banana pudding, a style I was trying for the first time — soft cream with banana tucked inside, paired with crunchy granola for a great combo! With the granola and banana, it felt like a healthy dessert :) ![Banana pudding scoop topped with granola](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-20-fkk6o-900.webp) ![Banana pudding showing banana pieces inside the cream](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-21-1imvd-900.webp) ### Classic financier And finally, the classic financier. Crisp outside, slightly chewy and soft inside — I enjoyed it a lot ^^ ![Close-up of the classic financier](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-22-9ogfy-900.webp) ![Cross-section of a classic financier cut in half](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-23-1e76o-900.webp) All three desserts had their own character while pairing beautifully with the cold brew, so if you visit Nerdy Blue Burrow, I recommend the signature set ^^ ![Table with cold brew and the three desserts](https://img.superchart.com/images/nerdyblue-burrow-wangsimni-decaf-coldbrew/nerdyblue-burrow-wangsimni-decaf-coldbrew-24-gi6ze-900.webp) ## Why Nerdy Blue Burrow is worth a visit in Wangsimni I had a relaxed evening tea time at Nerdy Blue Burrow, a Wangsimni café with real character, and it turns out this is a branch of 'Nerdy Blue' café in Cheongnyangni haha.
