Seongsu pizza date with meatball and bacon potato: Pizza Slice Seoul

In short

Where is Pizza Slice Seoul near Seongsu Station?

Pizza Slice Seoul is a slice pizza shop on the basement floor of 159 Achasan-ro in Seongsu-dong. Today my boyfriend and I came out for a long-overdue Seongsu date. We're both pizza lovers! Honestly, my boyfriend usually just goes along with whatever I want to eat, but at Pizza Slice Seoul he doesn't have to — we can each just get the slice we want! So here's my review of Pizza Slice, a Seongsu pizza spot 〰️

Today's pizza was bacon potato pizza, priced at ₩8,000. We ordered today's pizza, meatball pizza, buffalo wings (spicy), and a cola.

On one side of the shop, you could watch in real time as they stretched the dough and piled on the toppings with real care. The freshly baked pizza smell from the clean open kitchen filled the whole place — fun to watch and fun to eat, both at once.

Inside Pizza Slice Seoul: wood-toned room and seating

The Seongsu branch of Pizza Slice Seoul is a basement space with wood-toned interior that feels like a café. And honestly, isn't this clean interior just gorgeous? The moment we walked in, the tidy, woody atmosphere instantly put me in a good mood. It really feels like a café!

The heavy yet warm wood interior gives you a welcoming feeling! Sunlight fills the whole space, making it feel really fresh and clean. None of the typical greasy pizzeria vibe — it felt like stepping into a clean, emotional café, a healing space from the moment you walk in.

Sunlit seating area of the restaurant

There's quite a lot of seating too, so it would work well for couples, solo visits, or groups! I came with my boyfriend, and it really felt like a proper date after a while 🤍

How do the meatball pizza, bacon potato slice and buffalo wings taste?

The slices at Pizza Slice Seoul get reheated in the oven once more before serving! They come out bigger than your palm, so for one person, one pizza slice plus one side dish is just about perfect.

My pick was the meatball pizza 🩷 the meatballs tucked between every bite were so good! At first I thought it might be a bulgogi pizza, but nope, it was meatballs — my first time trying meatball pizza, and it was delicious.

This is the buffalo wings — salty and spicy, great to eat once you're getting a little tired of the pizza! The celery and mayo sauce on the side are a nice kick too.

My boyfriend says the bacon potato, drizzled generously with hot sauce, was his top pick!
