For a late lunch after 2pm, the order at Pizza Slice Seoul was a pepperoni slice at 7,000 won, a meatball slice at 7,800 won, today's pizza at 8,000 won (combination-style that day) and buffalo wings at 6,000 won. Even underground, a huge window wall kept the room bright and airy, making Pizza Slice Seoul an easy way to finish shopping and a meal in one Seongsu building. ## Good to know - **Address**: B1, 159 Achasan-ro, Seongdong-gu, Seoul - **Hours**: Daily 11:00–20:00 - **Pepperoni slice**: 7,000 won - **Meatball slice**: 7,800 won - **Today's pizza**: 8,000 won (combination-style on this visit) - **Buffalo wings**: 6,000 won - **Space**: Basement floor with a full window wall and an open kitchen *as written by the visitor on Sep 21, 2026* ![Seongsu Pizza Slice Seoul cover image](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-01-1yilc-1200.webp) > 📍Pizza Slice Seoul info > Address: 159 Achasan-ro, B1, Seongdong-gu, Seoul, South Korea > Hours: Daily 11:00–20:00 ## Where is Pizza Slice Seoul? Basement of the Seongsu This Is Never That and Kirsh building Seongsu is always crowded, but I still end up there again and again... because let's be honest, Seongsu means pop-ups and clothes shopping, right? That day too, I was busy wandering around and looking at everything! ![Walking around and exploring the Seongsu-dong streets](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-02-1yi6j-900.webp) While checking out This Is Never That and Kirsh, I went into the building and found out there was a pizza place in the basement! It's apparently the talk of Seongsu right now, so here's my review of Pizza Slice Seoul. I found out that the building with This Is Never That and Kirsh also runs a pizza restaurant on the side. ![Exterior of the Seongsu building with This Is Never That and Kirsh](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-03-121f8-900.webp) ![Entrance to the building where Pizza Slice Seoul is located](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-04-eldpe-900.webp) ![Stairs leading down to the basement pizza shop](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-05-y8bt0-900.webp) "Let's just grab a slice each for a late lunch," I thought casually as I headed down to the basement, but the vibe from the entrance onward was already so good. ![The entrance vibe of Pizza Slice Seoul](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-06-quclq-900.webp) ![Interior design of Pizza Slice Seoul](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-07-1ys9m-900.webp) ![Full view of the basement pizza shop's dining hall](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-08-zh049-900.webp) ## Still full at 2pm: how a basement room feels open at Pizza Slice Seoul It was already past the lunch peak, after 2pm, but I was surprised how many customers were still inside Pizza Slice Seoul. There were even foreign customers coming in nonstop — you could really feel its global popularity, wow. ![Customers inside the shop past 2pm](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-09-1ruqg-900.webp) ![Seating and tables at Pizza Slice Seoul](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-10-o6a65-900.webp) Basement restaurants are usually a bit stuffy, but this place has a large window-wall structure so it didn't feel cramped at all — very open and airy. ![The open, airy window-wall structure despite being underground](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-11-1nfb2-900.webp) ![View of the restaurant from a seat by the window wall](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-12-5m6ee-900.webp) That open feeling made it a really comfortable place to sit, and since the kitchen is open-style, it was fun watching them make and bake the pizzas right in front of us. ![The open kitchen baking pizzas](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-13-19ky2-900.webp) ![The order counter in front of the open kitchen](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-14-1wn0c-900.webp) ### Pizza Slice Seoul menu and prices ![Pizza Slice Seoul's menu board](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-15-1iebm-900.webp) ## Ordering pepperoni, meatball and today's pizza slices with buffalo wings For our late lunch, here's what we picked: ![Slice pizzas served for our late lunch](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-16-173zo-900.webp) ![Three slices of pizza with buffalo wings](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-17-16wni-900.webp) - ✔️Pepperoni slice (₩7,000) - ✔️Meatball slice (₩7,800) - ✔️Today's pizza (₩8,000) *combination-style that day - ✔️Buffalo wings (₩6,000) ![Close-up of the pepperoni slice](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-18-lfuc6-900.webp) ![Meatball slice and today's pizza slice](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-19-97r3e-900.webp) They reheated the pizza slices for us! Each slice was so big I thought it'd be perfect for coming alone and having one slice with a beer. ![A big pizza slice held in one hand](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-20-1qqdw-747.webp) We just wanted something light, but why was it this good? And with the spicy buffalo wings on the side, ![A plate of spicy buffalo wings](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-21-1ykoq-900.webp) the wings cut through the richness of the pizza perfectly, so we enjoyed every last slice. ## Hotel-grade restrooms in the Seongsu building After filling up, I went to the bathroom on the way out, and honestly, that's where I got impressed all over again — the restroom felt hotel-grade; big companies really do it differently... there was even air conditioning inside the bathroom. ![The restaurant's bathroom, complete with air conditioning](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-22-1sydt-900.webp) After the meal, we moved to the café right next door for coffee, then took the elevator straight up to the 2nd-3rd floors to finish our clothes shopping, haha. ## Is Pizza Slice Seoul worth it on a Seongsu shopping day? Honestly, Seongsu-dong has so many places to eat and so many pretty cafés that I always agonize over where to go! But when I stumble on a hip spot like this that's totally my taste, it puts me in a good mood for the whole day. ![The table and dining atmosphere after finishing the meal](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-23-12plg-900.webp) It was the perfect Seongsu outing — good food, shopping, and aesthetic vibes all in one place. Grabbing a light bite with slice pizza and chatting comfortably with a friend in a pleasant space left me very satisfied... next time I want to try every other pizza flavor one by one, haha. ![A shot taken while leaving Pizza Slice Seoul](https://img.superchart.com/images/seongsu-pizza-slice-seoul-late-lunch/seongsu-pizza-slice-seoul-late-lunch-24-16buu-900.webp) If you have a Seongsu-dong date or outing planned this holiday, please keep this in mind and have a great time! If you're looking for a pizza place with real character, away from the noisy main Seongsu street, I highly recommend Pizza Slice Seoul! 🍕 ## Where it is - Pizza Slice Seoul (피자 슬라이스 서울) - 159 Achasan-ro, B1, Seongdong-gu, Seoul, South Korea - 서울특별시 성동구 아차산로 159 지하1층 - 37.5430948, 127.0616748 - Google Maps: https://www.google.com/maps/search/%ED%94%BC%EC%9E%90%20%EC%8A%AC%EB%9D%BC%EC%9D%B4%EC%8A%A4%20%EC%84%9C%EC%9A%B8/@37.5430948,127.0616748,17z --- Superchart · https://superchart.com/en/@tiled-counter-ledger/seongsu-pizza-slice-seoul-late-lunch/ · https://superchart.com/llms.txt
