Words & Photos ©️ Yunne

Hello, everyone! 🩷

I'm travel blogger Yunne!

After work, my husband and I headed to Hongdae for a date night.

Since we didn't want to just grab dinner and go home,

we decided to challenge ourselves with an escape room!

We had already booked a slot at Deep Thinker, a super popular escape room cafe in Hongdae.

We played the theme "Ongi's Dream,"

and it was honestly so much fun!

Even on our way back home afterwards,

my husband and I couldn't stop talking about how cool the storyline was.

Hongdae Escape Room: Deep Thinker Basic Info

Deep Thinker is located at 23 Jandari-ro, Mapo-gu, Seoul,

right on the 4th floor.

There's an elevator,

which made it super easy and convenient to head up!

It's only about a 5-minute walk from Hapjeong Station, Exit 3!

Even though it's known as a Hongdae escape room, if you're taking public transit,

I highly recommend getting off at Hapjeong Station rather than Hongdae Univ. Station!

They are open from 10:00 AM

until 11:30 PM,

and you can easily book your slot on their official website.

Hongdae Escape Room Cafe Deep Thinker

Book your spot here!

Bookings open 2 weeks in advance from today,

and please note that canceling within 2 hours of your game time

will incur a cancellation fee, so make sure to double-check!

The escape room price is ~$17 per person!

English Translation Provided! Highly Recommended for English-speaking Friends

This theme involves a fair amount of movement,

and you'll swap your shoes for indoor slippers before entering!

Comfortable clothing is recommended,

but they even provide comfortable pants if you need a pair!

So we definitely recommend pants over skirts!

Slippers are neatly arranged

by size, so you can just grab a pair

that fits you perfectly and head on in!

One of the biggest highlights of Deep Thinker

is that they offer full English support.

The story prompts and clues in the theme

are provided in both Korean and English,

making it the perfect place to experience

Korea's amazing escape room culture with your global friends!

If you want to introduce escape rooms

to friends visiting Korea for the first time, this is the ultimate spot.

You get to fully experience the incredibly immersive Korean escape room style,

and doing it all without any language barrier

is exactly why I highly recommend this as a foreigner-friendly escape room in Hongdae.

"Ongi's Dream" – A Cute, Whimsical, and Zero-Fear Theme!

The theme we played at Deep Thinker is called "Ongi's Dream."

It's a super cute and charmingly designed theme,

and with absolutely zero horror elements,

even those who easily get spooked can comfortably enjoy the puzzles!

While 2 to 5 people can play together,

I think 2 players is the absolute sweet spot!

The play time is 65 minutes.

Since they run on a tight, continuous schedule,

please don't be late..!

I think they don't let you wait inside

to avoid any potential spoilers

for players currently in the rooms!

I highly recommend arriving

exactly 10 minutes before your booked time!

There were more rooms than expected—

about 6 to 7 rooms in total—

and the set design of each room was incredibly detailed and immersive.

The official difficulty is 3.5 stars,

and it definitely felt like that in reality!

It's not overly difficult,

so it's the perfect level to enjoy while solving.

After escaping, you can get

a cute Ongi magnet by participating in a review event.

You can also buy badges as souvenirs!

Highly Recommended: Deep Thinker for Hongdae Couple Dates and English-Friendly Room Escapes

Deep Thinker in Hongdae

perfectly ticks all three boxes:

a cute theme, a solid storyline, and English support.

They have lockers for storage,

so you can stash your bag, smartwatch,

phone, and other belongings inside

before starting your escape room adventure.

You fill out a waiver using a QR code,

read the story prologue for "Ongi's Dream,"

learn how to use the different locks,

and then start right at your reserved time!

They have a water purifier

and a restroom inside,

so it's very convenient to wash your hands

or use the restroom before or after the game!

I highly recommend this not just for couples on dates,

but also for introducing Korea's unique room escape culture

to your international friends.

If you want a fun, non-scary room escape

with a great storyline,

head to Deep Thinker's "Ongi's Dream" theme.

Escaped with 3 hints and just 39 seconds left! Honest Review

My partner and I used 3 hints

and escaped with just 39 seconds left!

​

It was a real close call,

which made it even more thrilling!

The storyline is so well-crafted

that it didn't just feel like solving puzzles;

it really felt like stepping into a storybook.

Even after escaping,

my husband and I kept talking about

how great the plot was and how much fun we had.

Once you escape, you can decorate your very own celebration board,

and put on some adorable cat ears and paws

to take the perfect proof-of-escape photos!

It's such a fun way to capture the memories.

I absolutely love escape rooms

that have these cute photo zones with props!

I really hope Deep Thinker opens up more themes soon!

We had such an amazing, fun-filled time!
