There's a huge variety of tables, from tables for two to tables for four, with wide spacing between seats that made it really comfortable. Through the floor-to-ceiling windows you can see lush green plants, so it was nice to eat while quietly soaking in the atmosphere. No wonder it's a Seongsu hotspot restaurant — the vibe was really great!

Pizza Slice has an open kitchen, so if you're lucky you might even get to watch the pizza being made in real time?!

![Spotlessly clean open kitchen](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-06-9fzr2-900.webp)

It was kept so spotlessly clean that I really liked it.

## Pizza Slice Seoul menu and slice prices

True to being a pizza-by-the-slice specialist, there's a huge variety of pizza types.

Among the pizzas that looked delicious, I ordered a white slice for ₩7,800, a mushroom slice for ₩7,400, garlic bread for ₩3,000, and a cider and a cola at ₩3,000 each. The prices felt a bit steep, but considering Seongsu-dong prices in general, it wasn't bad. Takeout is available too, in case that's useful.

## How fast do the slices arrive after ordering?

After ordering, there's a spot to the side where you can wash your hands, so I gave them a good scrub

![Hand-washing area inside the restaurant](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-11-1ph16-900.webp)

then grabbed cold drinks and sat down.

![Table set up with drinks](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-13-n7gv1-900.webp)

They reheat the pizza in the oven and it comes out really fast!

Each slice is on the larger side, so it'd probably be filling enough as a full meal on its own. I ended up splitting mine in half with a friend who came along!

(Forks and knives are right next to the ordering counter!)

## What does the white Hawaiian slice taste like?

Pizza Slice Seoul's white Hawaiian slice has snow-white melted cheese topped with pineapple, bacon, and onion.

![Thin-crust white Hawaiian pizza slice](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-16-1gzba-900.webp)

![White Hawaiian slice cut in half to share](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-17-187i2-900.webp)

The crust is on the thin side! That flavor where the sweet-tart pineapple juice bursts and mingles with the savory cheese and salty bacon — you know that taste, right??

To add some heat, I sprinkled on red pepper flakes!

## What does the mushroom slice taste like?

The mushroom slice has big, thickly-sliced mushrooms scattered evenly across the top, almost casually.

![Mushroom slice topped with large mushroom pieces](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-18-1l04p-1200.webp)

![Close-up of pizza slice topped evenly with mushrooms](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-19-11dys-900.webp)

![Mushroom slice sprinkled with red pepper flakes](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-20-c7cfk-900.webp)

Compared to the white Hawaiian I'd just eaten, this one is more strongly seasoned. Personally, this one suited my taste better! It's a pizza where the mushroom's texture and aroma really come through.

Since I love spicy food, I doused this one with a ton of red pepper flakes and hot sauce haha

## What style is the garlic bread at Pizza Slice Seoul?

Pizza Slice Seoul's garlic bread (₩3,000) is about the size of a clenched fist (for an adult woman). The round bread comes generously coated in garlic sauce.

![Garlic bread about the size of a fist](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-22-1kgcy-900.webp)

![Garlic bread cut in half showing the inside](https://img.superchart.com/images/seongsu-pizza-slice-seoul-shared-slices/seongsu-pizza-slice-seoul-shared-slices-23-vj5m9-900.webp)

When I cut it in half, it looked so much like chicken breast that I briefly thought I'd ordered the wrong thing, but nope, taking a bite confirmed it's definitely bread. Haha.

I'd assumed it would be like a Korean-style garlic bread, but there was no sweetness — it leaned strongly savory instead. The bread had a dense texture with a good chewiness. The garlic aroma was strong too, so you really get to enjoy that intense garlic flavor.
