Opening the sliding door by the window makes the atmosphere even better! ![Window seating with a sliding door](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-04-14rep-846.webp) The space itself is so pretty and pleasant that it is absolutely ideal for a Seongsu date. It is also great for meeting friends, and it is the kind of atmosphere that will earn you compliments if you bring your partner, haha. ![Iridescent entrance and seating area](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-05-x8t7p-900.webp) ![Dog-friendly window seating area](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-06-1kn7c-900.webp) ## A window seat with my dog You choose your seat as soon as you enter, and because we had a dog, we could only use the window-side seats! The staff welcomed us so warmly that I was in a great mood from the start. ![Iridescent ordering counter](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-07-1055w-900.webp) The staff help you order directly at the counter and explain the menu in great detail. The signature items are so unusual, so I loved that they kindly explained what each one tasted like while I was choosing. ![Iridescent menu information](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-08-o07jw-900.webp) ![Café menu with signature items](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-09-opkau-900.webp) ## From a perilla smoothie to pepper tiramisu The menu will make your eyes go wide. Starting with the signature citrus perilla-leaf smoothie, there is pepper tiramisu and Basque cheesecake, too. ![Perilla smoothie and dessert menu](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-10-1qrk0-900.webp) The prices are quite reasonable for a Seongsu-dong café, so it is easy to try several things without feeling burdened. For coffee, you can choose between acidic and nutty beans. ![Ordered drinks on a café table](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-11-9nuje-900.webp) ## A citrus perilla-leaf smoothie as refreshing as green grapes Our drinks finally came out. The presentation alone made me go, “Wow!” ![Citrus perilla-leaf smoothie presentation](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-12-1mlch-900.webp) The citrus perilla-leaf smoothie has a green hue, topped with a large perilla leaf and a slice of lemon. The moment I took a sip, I could not help but gasp—wow. ![Smoothie topped with perilla leaf and lemon](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-13-19dw8-900.webp) I expected the perilla aroma to hit hard, but not at all—it tasted like refreshing green grapes. ![Signature drink with sherbet on a perilla leaf](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-14-1ntb0-1200.webp) For a fun twist, you could put the sherbet on the perilla leaf and eat it like a wrap. It was much more delicious than I expected, which really surprised me! Haha. The aroma, texture, and finish were all wonderfully cool and refreshing. ![Decaf iced Americano](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-15-4lwx3-900.webp) ## A decaf iced Americano This is the iced Americano we ordered alongside it. I tried it with decaf beans, ![Clean-tasting iced Americano](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-16-r5qat-900.webp) and it had no acidity with amazingly good balance. It cleans up the palate so neatly—simply perfect. ![Café desserts and baked treats](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-17-1e948-900.webp) ## Next time, pepper tiramisu too There are also lots of desserts that make a nice light side. ![Torched cheesecake and baked treats](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-18-puse1-661.webp) Every baked treat looked delicious, and the cheesecake torched to order is famous, too. If I visit again, I absolutely have to try it with the pepper tiramisu next time, haha. ## A Seongsu café where atmosphere and flavor work in harmony Everything is perfect, from the drinks to the inventive menu lineup. I loved the refined interior, and even the kindness of the staff—everything works together beautifully. ![Iridescent café space and drinks](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-19-1gwyv-900.webp) It is an excellent spot that nails both value and quality, so it does not feel like a waste of money at all. It is for couples looking for an unusual date course around Seoul Forest in Seongsu-dong, anyone hoping to make special memories with friends, and people looking for a dog-friendly café. ![Quiet café space near Seoul Forest](https://img.superchart.com/images/seoul-forest-perilla-smoothie-iridescent/seoul-forest-perilla-smoothie-iridescent-20-1m0m5-900.webp) For anyone wanting to relax and recharge in a quiet atmosphere, I seriously recommend this place without hesitation. I think I will drop in like it is my regular mill every time I come to Seongsu-dong.
