Today's review is Pizza Slice Seoul. I recently went to Seongsu-dong and ended up at this hot spot, enjoying delicious slice pizza in a really sensory-rich atmosphere ✨ Check out the video for more too!

Exterior of Pizza Slice Seoul in Seongsu

Seongsu-dong has plenty of pretty cafés and stylish showrooms, but there's also fun in hunting down a good slice pizza spot to pair with a light beer or drink, no pressure attached! I got pulled in by the eye-catching interior and the smell of pizza as I was walking by.

Inside Pizza Slice Seoul: daylight through big windows and music

Interior lit by a large window

The first thing I felt walking into Pizza Slice Seoul was: this space is really sensory. Thanks to the big windows letting in sunlight like sunshine, the whole shop had a bright, cozy feel ☀️

On top of that, sensory speaker music wrapped around the space, so it felt like more than just eating pizza — like being in a hip, special place. You could tell every detail of the interior had been carefully thought through, and I kept taking photos while waiting for the pizza 📸

Handwashing area set up on one side of the shop

Since slice pizza is the kind of thing you casually pick up with your hands, hygiene really matters, right? Pizza Slice Seoul has a dedicated handwashing area set up on one side of the shop, and it was kept really clean and tidy.

Neatly arranged table in the shop

The overall shop hygiene and table cleanliness were perfect too, so I felt comfortable the whole visit. A place with both a sensory interior and solid hygiene made me want to come back.

  • Mushroom Slice (7,400 won)
  • Fries (4,000 won)
  • Zero-sugar cola

Jalapeno & Cream Cheese slice, 7,400 won

Jalapeño cream cheese slice pizza

One of the menu items I was most looking forward to — jalapeño and cream cheese pizza! The soft, rich flavor of the cream cheese spreads generously across the whole dough, and right when it might start to feel greasy, the spicy jalapeño pops in and cleans up the flavor. The balance of sweet-salty and spicy was fantastic, so it never got old and I finished it happily 🌶️🧀

Mushroom Slice, 7,400 won

Mushroom slice pizza

This mushroom pizza has the deep flavor and subtle aroma of mushrooms soaked well into the dough and cheese. Every bite had that clean, chewy mushroom texture, so anyone who likes a plain, savory pizza would definitely be satisfied! The dough itself was crispy outside and chewy inside, so I enjoyed it happily right down to the last bit of crust.

Fries 4,000 won and a zero-sugar cola

Crispy fries with zero-sugar cola

A side dish that's a must with pizza — fries! Crispy outside, fluffy inside, classic fry style, perfect to snack on between pizza bites. Paired with the fizzy zero-sugar cola, it made for a perfect combo 🥤
