# Daylit sunken basement slice pizza in Seongsu: Pizza Slice Seoul - By Aram (https://superchart.com/en/@napkin-fold-gyeonggi/) - Written Sep 20, 2026 - Local places › Restaurants › Seongdong, Seoul - Sponsored: This visit was sponsored by the business. - English edition: https://superchart.com/en/@napkin-fold-gyeonggi/pizza-slice-seoul-seongsu-sunken-basement/ - Also in: [한국어](https://superchart.com/ko/@napkin-fold-gyeonggi/pizza-slice-seoul-seongsu-sunken-basement/index.md) ## In short Pizza Slice Seoul is a slice pizza shop on the sunken basement level of 159 Achasan-ro in Seongdong, Seoul, a 10-minute walk from Seongsu Station Exit 2. This visit covered Today's Slice, a jalapeño and cream cheese slice (7,400 won), buffalo wings (6,000 won) and two drinks, and the sunken windows kept the basement dining room bright rather than dim. Because Pizza Slice Seoul sells by the slice instead of by the whole pie, it is an easy place to compare two flavors in one sitting. ## Good to know - **Location**: 159 Achasan-ro, B1, Seongdong-gu, Seoul (10-minute walk from Seongsu Station Exit 2) - **Hours**: Daily 11:00–20:00 (last order 19:30) - **Cheese slice**: 6,200 won - **Pepperoni slice**: 7,000 won - **Mushroom slice**: 7,400 won - **Jalapeño and cream cheese slice**: 7,400 won - **White Hawaiian slice**: 7,800 won - **Homemade meatball slice**: 7,800 won - **Buffalo wings (hot / snack)**: 6,000 won - **Garlic knots / fries**: 3,000 won / 4,000 won - **Pizza box / slice box**: 1,000 won / 500 won - **Seating**: Sunken basement level, open kitchen, hall with widely spaced tables - **Price reference**: ₩6,200 ≈ $4.5 · ₩7,000 ≈ $5 · ₩7,400 ≈ $5.3 (2026-09-21) *as written by the visitor on Sep 20, 2026* ![Featured photo of slice pizza at Pizza Slice Seoul in Seongsu](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-01-shox5-1200.webp) I was craving good pizza in Seongsu and went looking around, and that's how I ended up here! Pizza Slice Seoul! There are already so many great spots in Seongsu these days, but what drew me to this one was that instead of ordering a whole pizza, you can pick whichever flavors you want by the slice 😊 ## Where is Pizza Slice Seoul and what are its hours? ![Exterior of the Pizza Slice Seoul Seongsu location](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-02-zg1l7-966.webp) 📍Pizza Slice Seoul 159 Achasan-ro, B1, Seongdong-gu, Seoul ※10-minute walk from Seongsu Station Exit 2 ⏰Daily 11:00–20:00 (last order 19:30) ![View of the basement-level entrance on Achasan-ro](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-03-aaeec-966.webp) ![Pizza Slice Seoul entrance signage](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-04-btjh6-966.webp) The entrance itself is so stylish!

Walking in, I could see the pizzas being prepped at the open kitchen, and the interior felt spacious and relaxed, so it was comfortable to eat here. The gap between tables was generous too, which I really appreciated 👍❤️ ![Pizza Slice Seoul menu board with prices](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-07-1c8xc-966.webp) ## Pizza Slice Seoul menu and slice prices [Pizza] Cheese slice ₩6,200 Pepperoni slice ₩7,000 Mushroom slice ₩7,400 Jalapeño & cream cheese slice ₩7,400 White Hawaiian slice ₩7,800 Homemade meatball slice ₩7,800 Today's Slice - ask staff Pizza box/slice box ₩1,000/₩500 [Sides] Garlic knots ₩3,000 Fries ₩4,000 Buffalo wings (hot/snack) ₩6,000 [Extras] ₩1,000 Garlic dipping sauce Ranch sauce Hot chipotle sauce Pickles [Dessert] Soft serve ₩4,000 Cookie ₩3,500 [Drinks] Coca-Cola/Coca-Cola Zero ₩3,000 Sprite ₩3,000 Dr Pepper Zero ₩3,000 Fanta Pineapple ₩3,000 Homemade lemonade ₩4,000 [Beer] Budweiser ₩6,000 [Cocktails] ₩7,000 rum and cola rum and sprite malibu cola whisky and cola gin and sprite american lemonade habush and cola habush and lemonade We ordered one slice of Today's Slice, one jalapeño & cream cheese slice, buffalo wings, and two drinks!

(for light eaters, at least) ![Dining hall table with generous spacing between seats](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-08-1ogqp-966.webp) ![Tabasco, oregano, and other sauces on the table](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-09-1fxvb-966.webp) ## Table sauces and the sunken basement seating in Seongsu Every table had ketchup, Tabasco, oregano, pepper, and red pepper flakes! With so many sauces to play with, you could turn one pizza flavor into several. Even though the restaurant is in the basement, the sunken structure means there are windows, so it never felt dark at all. ![Basement seating lit by light through the sunken windows](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-10-ml7na-966.webp) ![A slice of Today's Slice pizza](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-11-1305l-966.webp) ![Slice pizza topped with jalapeño and cream cheese](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-12-1w9zx-966.webp) ![Buffalo wings ordered as a side](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-13-1qctq-966.webp) ## How Today's Slice, the jalapeño and cream cheese slice and buffalo wings tasted Our order arrived! Part of the fun of Today's Slice is not knowing which pizza it'll be each day! The pizza came out warm, and the crust had a chewy yet crisp texture I liked, with the cheese and toppings working well together 👍 Since I love spicy food, I ordered the jalapeño & cream cheese slice! The jalapeño's kick combined with the creamy cream cheese worked better than I expected! It added spice to what could otherwise be a rich, heavy pizza, and honestly I just kept reaching for more 😊 The buffalo wings we ordered alongside the pizza made a great side too! Eating the wings together with the pizza rather than just pizza alone made the meal feel more filling and satisfying — a perfect full meal haha. ## Ordering by the slice from the display at Pizza Slice Seoul ![Slice pizzas lined up at the order counter](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-14-1sa2b-966.webp) The pizzas are laid out right at the ordering counter like this, so it seemed like they reheat it right away as soon as you order! Being able to see the pizzas with my own eyes and pick what I wanted was great 💛 And above all, being able to order individual slices instead of a whole pie seems like the biggest advantage of Pizza Slice Seoul! It'd be great for a group who each want to pick their own flavor and share, and also for people like me who want to compare two flavors side by side. ![Small handwashing sink and hand soap by the bussing station](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-15-90e5l-966.webp) After finishing up and heading toward the bussing station, there was even a little handwashing sink there! + Hand soap was, of course, provided too. ![Closing shot of the Pizza Slice Seoul restaurant](https://img.superchart.com/images/pizza-slice-seoul-seongsu-sunken-basement/pizza-slice-seoul-seongsu-sunken-basement-16-fknoj-966.webp) If you're craving pizza in Seongsu, give Pizza Slice Seoul a try — a Seongsu-dong pizza spot where you can pick and choose a variety of slice flavors to your taste!
