We shared the ₩16,000 Thai Pho Piset Special and the ₩14,000 gamjatang pho, with the pork-bone-and-egg bowl standing out most. A fun choice for a more unusual lunch than standard pho. ## Good to know - **Address**: Room 203, 1F, 16 Ttukseom-ro 9-gil, Seongdong-gu, Seoul, South Korea (서울 성동구 뚝섬로9길 16 1층 203호) - **Hours**: 11:30–22:00 - **Break time**: 15:00–17:00 - **Regular closing day**: Sunday - **Parking**: Check before visiting whether building parking is available. - **Thai Pho Piset Special**: ₩16,000 - **Gamjatang pho**: ₩14,000 *as written by the visitor on Sep 12, 2026* I went out for lunch with a close younger friend I was meeting in Seongsu-dong for the first time in a while. I wanted a warm bowl of pho rather than anything too heavy that day, and every time I passed through the Seongsu-dong alleys, this place caught my eye. ![Visiting Thanon55 in a Seongsu-dong alley](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-01-1ohty-1200.webp) So I finally visited Thanon55 (타논55), somewhere I had wanted to try. ![The space at Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-02-741dk-900.webp) ![A view of the Thanon55 restaurant](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-03-4ttma-900.webp) The space was pretty, and the menu had dishes that were a little different from the pho you usually eat, so I had been curious about it. ![The exotic atmosphere at Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-04-1r1mm-900.webp) ![Thanon55 with a Thailand-travel feel](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-05-f9y52-900.webp) It felt like a little trip to Thailand~ ## A Thai atmosphere tucked into a Seongsu-dong alley Thanon55 is tucked away in an alley in Seongsu-dong. ![Thanon55 in a Seongsu-dong alley](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-06-ig0ur-900.webp) Even from the outside, it had that distinctive, exotic feel of a Thai restaurant, so it subtly caught my attention whenever I passed through the alley. ![The exotic exterior of Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-07-qw38q-900.webp) ![Exterior view of Thanon55 in Seongsu-dong](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-08-123dt-900.webp) Once inside, the atmosphere was really quite pretty too. ![The interior atmosphere at Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-09-1ekbx-900.webp) The distinctive Seongsu-dong sensibility and a Thai local feel were nicely blended, so even while eating, it felt a bit like being on a trip. ![The Thai local feel of Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-10-2ltb7-900.webp) More than anything, I noticed that Thai staff were preparing the food directly in the kitchen that day. Seeing them cooking among the Korean guests somehow made it feel even more like a local restaurant. ![The kitchen and dining area at Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-11-lxals-900.webp) That is probably why it seemed like a good fit for anyone looking for something a little different in Thai food around Seongsu. ## What was the Thai Pho Piset Special like? We ordered two dishes. ![Two pho dishes ordered at Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-12-jrnoj-900.webp) They were the Thai Pho Piset Special for ₩16,000 and the gamjatang pho, one of the best-selling dishes, for ₩14,000. ![Thai Pho Piset Special](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-13-lwwep-900.webp) First up was the signature Thai Pho Piset Special. The name alone made it seem like I would get to try a proper Thai-style pho, so I ordered it, ![Signature Piset Special pho](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-14-11to7-900.webp) and it did feel a little different from typical pho. I liked being able to enjoy distinctly Thai aromas and flavors, and it seemed like a good choice when you want a lunch in Seongsu-dong that is a little more unusual than the standard options. ## Gamjatang pho with pork bone and egg But the dish that impressed me even more that day was the gamjatang pho. ![Gamjatang pho at Thanon55](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-15-12tqj-900.webp) ![Best-selling gamjatang pho](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-16-in1xc-900.webp) I was intrigued by the name because it brings together gamjatang (pork-bone soup) and pho, and it was much more generous than I expected: there was plenty of meat attached to the large pork bone. ![Gamjatang pho with pork-bone meat](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-17-1876o-900.webp) Gently pulling the meat from the bone and dipping it in the soy sauce served alongside was delicious. Adding the spicy chili on the side changed the flavor again, and it went well with the meat. Above all, this pho did not just come with meat—it was topped with an egg too. ![Gamjatang pho topped with an egg](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-18-1m7lw-900.webp) The yolk was cooked beautifully—not too done and not underdone—so it looked great as well, ![Egg and noodles in gamjatang pho](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-19-15l02-900.webp) ![Pho with meat and egg](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-20-1msph-900.webp) and eating the noodles, meat, and egg together made for a really satisfying combination in one bowl. With noodles for carbs plus meat and egg, it was more than enough for lunch. ![Gamjatang pho served with broth](https://img.superchart.com/images/seongsu-thai-noodle-lunch-tanon/seongsu-thai-noodle-lunch-tanon-21-17chk-900.webp) The broth was the kind I kept spooning up, and I almost finished it all, but I was too full—sadly, I had to leave a little broth behind, haha. ## An easy lunch spot in Seongsu-dong I ate here while catching up over all sorts of things with my younger friend, whom I had not seen in a while, and the fun menu gave us plenty to talk about throughout the meal. I had always wondered about this place after passing it whenever I was in the area, and now that I had tried it, I understood why I had been so curious. Especially if you want to try something a little more unusual than everyday pho, it is worth stopping by as a good pho spot in Seongsu. A nice place to visit when you want a light lunch with a friend or partner in Seongsu-dong and want to try something new. ## Where it is - Thanon55 (타논55) (타논55) - Room 203, 1F, 16 Ttukseom-ro 9-gil, Seongdong-gu, Seoul, South Korea (서울 성동구 뚝섬로9길 16 1층 203호) - 서울특별시 성동구 뚝섬로9길 16 1층 203호 - 37.5396694, 127.0564402 - Google Maps: https://www.google.com/maps/search/%ED%83%80%EB%85%BC55/@37.5396694,127.0564402,17z --- Superchart · https://superchart.com/en/@seoul-nearby-plates/seongsu-thai-noodle-lunch-tanon/ · https://superchart.com/llms.txt
