Attention, everyone looking for a restaurant with a great atmosphere in Seoulsup!! 🤎 Today I'm sharing my visit to Rabbit Castle Seoulsup (래빗캐슬 서울숲), a Seoulsup restaurant I was so, so happy with!

Let me start with the conclusion: from the atmosphere to the taste, the menu set-up and the portions, there was nothing to be disappointed about. I especially want to recommend it to couples looking for a restaurant for a special-day date or an anniversary. 🥰

What is the exterior of Rabbit Castle Seoulsup like?

From the outside, Rabbit Castle Seoulsup feels like a little cottage where Peter Rabbit from the storybooks might live. 🐰🌿 It's cute but also warm and cozy, and I found it really charming.

There are lots of pretty restaurants these days, but Rabbit Castle has a fairy-tale feel of its own, so it felt even more special. The exterior is decorated so prettily that my expectations were already sky-high before we even went in. 🤎

Is the inside of Rabbit Castle Seoulsup clean and cozy?

The interior of Rabbit Castle Seoulsup was even, even, even prettier than the exterior, and above all it was really clean and pleasant!! It was full of that cozy, warm feeling, like stepping into the little cottage where Peter Rabbit lives. Every corner was so nicely decorated that just looking around was fun, and the whole interior was simply lovely.

Besides the pretty decor, the space itself was very clean and comfortable, so I was in a good mood all through the meal. It's great as a special date spot, but I'd also recommend it for family gatherings, blind dates, get-togethers with friends and wedding invitation meetups. For occasions where atmosphere matters, like a blind date or an anniversary, I think you'd be even happier here. 🥰

What does the steak set for two at Rabbit Castle Seoulsup include?

The steak set for two at Rabbit Castle Seoulsup is built by choosing your dishes, and we picked three: squid ink oil pasta, ratatouille gnocchi and the house steak. You get to enjoy pasta, gnocchi and steak, and the portions were much more generous than I expected.

  • ❤️ Squid ink oil pasta
  • ❤️ Ratatouille gnocchi
  • ❤️ House steak

So those are our three picks, haha. What really surprised me was how solid the set is!! Restaurants with a nice atmosphere can be a bit disappointing in portion for the price, right? Rabbit Castle wasn't like that at all.

For this price, this line-up and this much food, isn't that really great value?! The quality of every dish was great too, so I was satisfied the whole way through. I think ordering the steak set would be perfect for couples on a special date or anniversary. 🤎

Squid ink oil pasta: slightly spicy, so it never gets heavy

The squid ink oil pasta at Rabbit Castle Seoulsup has a gentle spiciness that cuts the richness, and it was better than I expected. I was curious what a squid ink oil pasta would taste like, and I was surprised at how good it was from the very first bite.

It keeps the nutty, rich flavor oil pastas are known for, while the slight spiciness wipes away the greasiness. Thanks to that, I never got tired of it and kept enjoying it. It has a special charm unlike an ordinary oil pasta, which made it more memorable. It also paired really well with the steak and gnocchi. I recommend trying the squid ink oil pasta at least once!! 🖤

Ratatouille gnocchi: vegetables blended with real elegance

The ratatouille gnocchi at Rabbit Castle Seoulsup is the one I personally ate with the most amazement!! This one was also seriously awesome. ❤️ Ratatouille is a dish with lots of different vegetables, right? But how can the vegetables in Rabbit Castle's ratatouille gnocchi come together so elegantly and deliciously! It felt completely different from the vegetable dishes I usually eat.

Each vegetable keeps its own charm while everything blends together harmoniously, and the match with the gnocchi was perfect. With every bite I couldn't help saying, "Wow, this is really good!" Haha, I don't know how many times I shouted that it was delicious while eating.

It tastes different from the gnocchi you usually get, which made it even more impressive, and this dish alone makes me want to come back to Rabbit Castle. The ratatouille gnocchi is a really, really strong recommendation too!!

House steak: no need to worry about portion, and cooked perfectly

The house steak at Rabbit Castle Seoulsup was much more generous in person than in the photo, and really tender! 🥩 When ordering, I actually worried the steak might be a little small. But once it arrived, that worry vanished completely! It feels like the photo just can't capture the real portion?!

The doneness was perfect too, and I was impressed throughout. It was tender, never tough or dry, and the meat itself was so tasty that I was really satisfied. Even while eating the steak I kept saying, "Wow, this place is really good!" Haha. Generous portion, perfect doneness and great taste, so there was nothing to complain about! If you love steak, please try it.

Rabbit Castle Seoulsup satisfied me on atmosphere, taste and value, so I strongly recommend it for an anniversary date. Restaurants with pretty atmosphere can sometimes disappoint on taste, but here the atmosphere is amazing, the food is amazing, and even the set-up and portions are amazing! I enjoyed all three dishes so much that it was hard to pick just one.

Especially the steak set: considering the price, the line-up, the portions and the quality, I felt the value was excellent. You can enjoy tasty food in a cozy space like Peter Rabbit's cottage, so it's perfect for a special day, right? 🐰🤎 Besides dates, I'd strongly recommend it for anniversaries, family gatherings, friend meetups, blind dates and wedding invitation meetups.

A walk in Seoulsup after the meal

There's one more reason I recommend Rabbit Castle Seoulsup! You can take a walk in Seoulsup after your meal. 🌿 Having a nice meal at Rabbit Castle and then strolling leisurely through Seoulsup seemed like a perfect date course.

On a nice day especially, spending the day walking in Seoulsup and taking pretty photos sounds wonderful. If you're thinking about a Seoulsup date course, I really recommend this one: eat at Rabbit Castle, then walk in Seoulsup!
