Instead of the somewhat cold, fast-food-joint feeling you usually get from pizza places, the whole space was full of a warm, refined atmosphere.

Stylish, sentimental furniture and lighting were arranged with just the right amount of subtlety, making the entire space feel both hip and luxurious. Natural light pours in beautifully by the windows, so simply setting your food down at a window seat gives you an instant profile-worthy shot.

The tables were spaced wide and comfortably apart, so it was the perfect environment to chat and eat without worrying about other people. Most memorable of all, from the moment I walked in until I left, the owner and staff greeted me brightly and kindly.

How big is a Pizza Slice Seoul slice, and what is the crust like?

Pizza Slice Seoul has an open kitchen, so you can watch with your own eyes as the pizzas get baked with fresh ingredients — which built a lot of trust. After ordering and a short wait, out came a pizza plated beautifully, and my jaw dropped the second I saw it in person!

One slice big enough to hide your face

When you hear "pizza slice," you'd usually picture a teasingly small piece, right? But at Pizza Slice Seoul, a single slice is genuinely big enough to fully cover a person's face!

It's the kind of generous size that feels like it was cut straight from a full large pizza, so just one slice is enough to fill up most adults.

The crust isn't ordinary either. Fresh out of the oven, the bottom and edges were crisp and crackly, while the inner bread kept a chewy texture, making it the kind of magic crust where you eat every last bit of the crust, nothing wasted.

How the cheese, pepperoni and jalapeño cream cheese slices taste

On this visit at Pizza Slice Seoul, I had three kinds: Cheese Slice for ₩6,200, Pepperoni Slice for ₩7,000, and Jalapeno & Creamcheese for ₩7,400. Each one had such a distinct charm that you won't regret picking any of them!

Cheese Slice (6,200 won)

This is the most basic pizza there is — cheese pizza! It's true to the basics, with the salty, rich, savory flavor of the cheese filling your mouth. Sprinkle on some of the table oregano powder or crushed red pepper to taste, and the richness gets cut right through while an upscale umami flavor bursts out. The balance between the crispy crust and savory cheese is the best!

Pepperoni Slice loaded with pepperoni

Pepperoni Slice (7,000 won)

This is an Instagram-worthy pepperoni pizza from the very first glance! Big, generous pieces of salty pepperoni ham are piled on top, showing off the classic look of an authentic American/Tokyo-style pizza. The harmony between the salty pepperoni and crispy crust is perfect, the kind of flavor that instantly makes you crave a cold ade or a beer. The pepperoni's signature umami pairs really well with the crust.

Jalapeno & Creamcheese (7,400 won)

This is the definitive sweet-salty-spicy menu that will target the taste buds of anyone who loves spicy food! The soft, savory cream cheese, which could easily be too rich, gets cleaned right up by the sharp, spicy jalapeño, so you can enjoy it cleanly right down to the last bite. This spicy-sweet, savory combination is a must-try specialty I'd highly recommend when you visit Pizza Slice Seoul!

Every table has hot sauce, ketchup, red pepper, and oregano seasoning neatly set out, which was also a real charm — you can adjust the seasoning to your own taste and enjoy the pizza in all kinds of ways.
