## In short

Pizza Slice Seoul is a slice pizza shop on the basement level at 159 Achasan-ro in Seongsu-dong, Seoul, where oversized pizzas are sold one slice at a time. On this visit the order was three slices to go — pepperoni, jalapeño cream cheese and homemade meatball — with the pepperoni salty and deeply savory and the jalapeño cream cheese's sharp bite cutting the richness. Pizza Slice Seoul works just as well for a single slice eaten alone as for a mixed box taken home.

I was hanging out in Seongsu-dong and trying to figure out where to grab a bite when I ended up at Pizza Slice Seoul. There are so many good restaurants and cafés in Seongsu-dong that after a whole day of wandering around, sometimes you just want something simple to eat. That's exactly when Pizza Slice Seoul comes in handy.

As the name suggests, this place sells big pizzas one slice at a time, so it's totally fine to go solo. Ordering a whole pizza can be too much for one person, but here you can pick whichever flavor you're craving and order just a slice — I loved that. It's a great spot if you're looking for somewhere to eat alone in Seongsu-dong, or if you want a quick meal while shopping or sightseeing!

## Where is Pizza Slice Seoul, and what is the shop like?

Pizza Slice Seoul is located on the basement level of Achasan-ro in Seongsu-dong. Even the exterior is bright white, so it really catches your eye.

The moment I walked in, what struck me was how spacious and clean the place felt. The overall bright white interior makes the space feel even bigger, and the vibe is tidy yet comfortable. You might picture pizza shops as a bit casual and cluttered, but Pizza Slice Seoul's roomy layout made it easy to sit and eat at a relaxed pace.

It felt like a good place to take a break and grab a slice while wandering around Seongsu-dong, and just as comfortable for a solo meal! Above all, the generous table spacing made it feel just right whether you're grabbing a quick bite or settling in for a proper meal.

## How big is one slice, and which three flavors were chosen?

The pizza at this Seongsu pizza spot Pizza Slice Seoul is known for its generous size. Even ordering just one slice, it turns out bigger than you'd expect and pretty filling. And since they sell by the slice, you get the added bonus of trying several flavors in smaller amounts.

This time I wanted to try a variety of flavors, so I ordered three: pepperoni pizza, jalapeño cream cheese pizza, and homemade meatball slice. Each has different flavors and toppings, so it's fun to alternate between bites!

There's a handwashing area inside the store, so it's convenient — no need to go all the way to the restroom!

## Pepperoni slice from Pizza Slice Seoul, eaten at home

I went with takeout! There were quite a lot of takeout and delivery customers too.

This Seongsu pizza spot Pizza Slice Seoul packs everything neatly for takeout too! First up, the pepperoni pizza I ordered as a default. You really can't skip pepperoni when it comes to pizza, right? The salty flavor of the pepperoni blended well with the savory cheese, giving that rich, distinctive American-style pizza taste. In particular, the salty, deep flavor from the pepperoni went so well with the pizza that I kept reaching for more.

### Jalapeño cream cheese slice: how spicy is it?

This is the jalapeño cream cheese pizza. The savory, smooth cream cheese combined with the spicy kick of jalapeño made for a pretty great pairing. Cream cheese alone can get a bit heavy, but the jalapeño's sharp bite cuts through that greasiness here and there. Personally I like bold flavors, so I really enjoyed this one.

### Homemade meatball slice at Pizza Slice Seoul

The homemade meatball slice had meatballs in it, so it felt more substantial than your typical pizza. The deep, rich flavor unique to meat toppings made even one slice pretty filling. It's a different kind of meaty flavor from the pepperoni, so it was great to order alongside the other pizzas when mixing things up.

## Is Pizza Slice Seoul good for solo dining and takeout in Seongsu?

Pizza Slice Seoul, a solo-dining spot in Seongsu-dong, lets you order just one slice of whatever you want, or pick several kinds to try. It's a great fit if you're looking for somewhere to eat alone in Seongsu-dong, and it also works well if you visit with a friend and each pick your own favorite flavor to share. It's good for taking out and eating comfortably at home too.
