Seongsu pizza shop, two slices with Tabasco: Pizza Slice Seoul

Where is Pizza Slice Seoul in Seongsu?

Pizza Slice Seoul sits in the basement level of a building at 159 Achasan-ro, Seongdong-gu, Seoul. It's easy to spot from outside — a big 'PIZZA SLICE' sign and a red pillar mark the entrance. The white building with its bold red accent gave off a pretty hip vibe right from the doorway.

The same building houses thisisneverthat and Kirsh, so it's a good stop after a bit of shopping.

Even though it's a basement shop, natural light reaches inside, so it never felt dark or cramped. Hours can change, so it's worth double-checking on Naver Map before you go.

Picking oversized slices flavor by flavor

Walking in, I found a glass display case lined with whole pizzas.

The kitchen is open too, so you can watch the pizzas being made and baked — even the dough looked like it's prepped in-house.

The menu was varied: cheese slice, pepperoni slice, mushroom slice, jalapeño and cream cheese slice, white Hawaiian slice, homemade meatball slice, and more.

I liked that you don't need to order a whole pie — you can pick a different flavor for each slice.

It's a great setup for anyone who wants to try a few flavors in small amounts, or for a light solo meal.

The slices were seriously large — the moment I saw them in the case, I thought of the New York-style slices you see in American movies.

Pepperoni slice: the hard-to-miss basic

First up was the pepperoni slice, about as classic as pizza gets. A generous layer of pepperoni sat on top of the big slice, with cheese melted just right. One bite in, the salty, rich pepperoni flavor paired well with the savory cheese.

The crust was on the thin side, but the edges were baked to a nice chewy-crisp finish. The topped center wasn't overly soggy either, which made folding and eating the big slice satisfying.

If you're not sure what to order, starting with pepperoni is a safe bet you won't regret. Familiar but well-executed, it's an easy pick if you're hunting for a good pizza spot in Seongsu.

The jalapeno slice, with a spicy kick

The other slice came topped with jalapeño and generous toppings. It had a more complex, spicier flavor than the pepperoni, and switching back and forth between the two kept things from getting repetitive.

The jalapeño's sharp kick balanced out the cheese's richness and the pizza's greasiness nicely. If you like spicy pizza, take a look at the case and go for something with jalapeño.

The table also had Tabasco, red pepper flakes, and oregano, so you can season to your own taste.

Why the garlic knots are worth adding

These are small knots of pizza dough baked with plenty of garlic butter and herbs — golden brown outside, chewy inside. The moment I opened the bag, a savory garlic smell drifted up, working up my appetite before the pizza even arrived.

They were salty and fragrant on their own, but they'd especially satisfy anyone who loves pizza crust. What could be a plain crust turns into something as enjoyable as garlic bread — memorable in its own right, not just a sidekick to the pizza.

They're also priced lower than a slice of pizza, making them an easy add-on, and there's enough of them to share between two people.

Good for a solo meal or a Seongsu date

Since Pizza Slice Seoul lets you order by the slice, it's an easy solo visit, and with a group, everyone can pick something different and share.

Beyond pizza, they also sell soft drinks, beer, and cocktails, so it's a good spot for pizza and beer too. The clean interior — white tones with red accents — makes it a nice casual stop during a Seongsu date.

A single slice isn't exactly cheap on its own, but the slices are big and you can mix and match as many flavors as you want — that's this place's edge.

Pizza Slice Seoul: the verdict

Pizza Slice Seoul is a solid pizza spot in Seongsu where you can pick and choose big slices to your taste. The salty, savory pepperoni pizza is a hard-to-fail classic, and the jalapeño slice's spice kept it from feeling greasy all the way through. I especially recommend adding the garlic knots, with their strong garlic butter and herb aroma, as a side.

If you're shopping around Seongsu-dong and want a simple meal, or you're looking for a solo-friendly hot spot in the neighborhood, stop by Pizza Slice Seoul and try a giant slice.
