Where is Pizza Slice Seoul near Seongsu Station?

Pizza Slice Seoul is a slice pizzeria on the basement level of 159 Achasan-ro, Seongdong-gu, Seoul, just 430 meters from Exit 2 of Seongsu Station, making it a great walk-to spot. It's open daily from 11:00 to 20:00 with last order at 19:30, and there's no parking.

I had plans in Seongsu-dong after a long while and was racking my brain over where to go, when I remembered a place that's been buzzing on Instagram and blogs lately. Pizza Slice, a trendy slice pizzeria near Seongsu Station! Even the entrance leading down to the basement level had a hip vibe to it, giving off exactly the kind of sensory mood you'd expect from a Seongsu-dong hotspot restaurant, and it got my expectations up before I even walked in.

Vibes~~~

What is the basement space at Pizza Slice Seoul like for three people?

Walking inside, the space was cleaner and more pleasant than I expected. The lighting wasn't too bright, just soft and subdued, and it blended perfectly with the music playing inside for an overall hip atmosphere.

The tables were spaced quite generously, with cozy spots for solo diners as well as tables for groups, so the three of us could sit comfortably and chat without any awkwardness. Since the pizza comes by the slice, it's perfect for picking whatever you like and trying a variety. The three of us each chose a different slice, ordered three total, and paired it with a Coca-Cola to wash it all down.

Nice and wide table spacing~ super pleasant space!

They have baby chairs too!

Every table has sauces set out!

What we ordered at Pizza Slice Seoul and what it cost

• Pepperoni Slice — ₩7,000
• Homemade Meatball Slice — ₩7,800
• Mushroom Slice — ₩7,400
• Coca-Cola — ₩3,000

I figured slice pizza would just be a light snack, but seeing them arrive, the size was way bigger than expected — plenty for a full, satisfying meal.

Pepperoni slice, 7,000 won: the best of the three

The pepperoni slice was the one everyone was most excited about! One bite in and I was blown away by the crispy, well-baked crust. The bottom was crunchy while the inside stayed moist and never dry or tough, and the salty, slightly spicy pepperoni flavor spread thick and heavy across the whole mouth. Of the three slices we ordered today, this one won hands down!! Pepperoni really is the classic pizza cheat code that never fails.

Meatball slice, 7,800 won: piled with homemade meatballs

Next up, the meatball slice caught the eye with its thick, hearty look. Big homemade meatballs were piled on generously, giving the bite a rich, fun texture. The deep meaty juices paired beautifully with the thick tomato sauce, and just one slice felt filling. If you love that heavy, deep American-style pizza flavor, this one's for you!

Mushroom slice, 7,400 won: the mild, balancing pick

And finally, the mushroom slice showed off a light yet sophisticated flavor. It was generously loaded with mushrooms, and every bite brought that distinct fragrant aroma and chewy texture blending nicely with the savory cheese. Not too intense, with the mushrooms' deep natural flavor still front and center, it worked as a great palate balancer between bites of the salty pepperoni.

Sipping on the fizzy cola between bites of pizza made for a perfect combo. It cut through the greasiness so cleanly that the pizza just kept disappearing — pure magic~~

Is Pizza Slice Seoul worth it for a meal with friends in Seongsu-dong?

Overall, the interior was really pleasant, and the music selection and stylish design made me feel good the whole time I was there. The staff were kind too, and the place was clearly kept very hygienic, which made everything even more comfortable to enjoy.

With the three of us sharing bites of whichever slice we each picked, the plates were wiped clean before we knew it. This is the place to go in Seongsu-dong when you want a light, tasty pizza with a cold drink, or when you want to spend a fun time with friends in a trendy, atmospheric space.

I bet a lot of people would agree pepperoni is the best menu item here, just like we did.

The bathroom was also super clean!

They even have a spot to wash your hands after eating — the best!

Trash disposal was well organized too~ and the elevator was so cute I had to check it out haha.

Made eye contact with a dog haha; looks like dogs can come in too! A successful Seongsu-dong hotspot restaurant experience, enjoying great slice pizza in a hip atmosphere — Pizza Slice! Next time I'm in Seongsu-dong, I'll happily come back for that pepperoni. A satisfying food adventure, the end!
