Sold-out slices at 5pm in Seongsu pizza shop Pizza Slice Seoul

In short

Pizza Slice Seoul is a New York-style slice pizza shop on basement level 1 of a building on Achasan-ro, near Seongsu Station in Seongdong, Seoul. Arriving with my sister around 5pm, we ate three slices — pepperoni 7,000 won, jalapeño and white cream cheese 7,400 won, and homemade meatball 7,800 won — and several other kinds were already sold out that late in the day. Each slice at Pizza Slice Seoul is bigger than an adult woman's fist, so it is the right place on a day when a whole pie feels like too much.

Pizza Slice Seoul: a slice-only pizza shop one floor below Seongsu Station

My sister and I were out in Seongsu today so we dropped by Pizza Slice :-> As the name suggests, this place only sells pizza by the slice haha! And there were so many different kinds!

Stairway entrance going down to basement level

It's underground, so we headed down the stairs haha

Staircase corridor leading to the basement

Once you go down, there's a door like this!

Right as you walk in, there's a restroom up front

And the shop is on the right! There are waiting seats in the corridor too, so you can sit down while waiting if it's full!!!

What the Pizza Slice Seoul interior looks like: wood tones and red

Isn't the interior so full of atmosphere?! Such a hip vibe ❤️ I love the combination of wood tones and the red that reminds you of pizza. There's even a slight feeling of being overseas.

View of seating with lighting inside the shop

There are also two-seat tables like this attached to the wall haha The lighting is great too, this being a popular spot — perfect for snapping photos for Instagram 👍🏻💛

Menu and display near the counter

Everything sits inside a showcase, which is nice because it's easy to see and no dust gets in 👍🏻 I visited around 5pm and a few varieties were already gone ㅠㅠ I'd recommend going early!!! There was just one jalapeño slice left so I grabbed it right away 😁

Hand-washing area with hand wash and towels

There's also a spot where you can just wash your hands, so you don't have to go all the way to the restroom!!! Hand wash and towels are provided too — very thoughtful 💯

Extra chairs and a baby chair

There are extra chairs and even a baby chair, so it's fine to come with kids!

Black pepper, red pepper, ketchup, and hot sauce on the table

On each table there's black pepper, red pepper, ketchup, hot sauce, and other sauces ready to go haha And there are paper towels at every table, which is convenient 🤩

The drinks corner

It seemed like drinks might be refillable but I'm not totally sure ㅠ.ㅠ Worth a try 〰️〰️😉

Jalapeño and white cream cheese slice, 7,400 won

The jalapeño & white cream cheese pizza — the spiciness of the jalapeños and the smoothness of the cheese make a perfect combo haha I usually love spicy food, so a pizza with jalapeños studded all over it like this was right up my alley

Homemade meatball slice, 7,800 won

The homemade meatball pizza — maybe because it's homemade, the meatballs were huge and delicious haha

We grabbed a knife from the counter to split this one in half with my sister, and drizzled on the hot sauce from the table too. It tasted even better with the hot sauce on it!!!🫠

Pepperoni slice, 7,000 won

The pepperoni pizza — a strongly salty, New York-style flavor. Feels like it would go really well with beer. They sell Budweiser too, so definitely try it with a beer 😉

A place that shows off the essence of New York-style pizza! A spot with a hip atmosphere where you can pick and choose different slices to your taste. If a whole pizza feels like too much, come to Pizza Slice Seoul 〰️🩷
