If someone asks me where to get proper lasagna in Ulsan,
I don’t even hesitate. It’s Lasagna 5F (라자냐5F), right across from Taehwagang National Garden.
I’ve been coming here since the early days,
and these days you pretty much have to expect a wait.
Quick heads-up about the name.
The “5F” made me think it was on the fifth floor the first time too.
It’s not. 5F is just the name, and the place sits on the ground floor.
Apparently everyone glances upward at least once before finding the door.
The basics
The address is 25 Singi 4-gil (신기4길), Jung-gu, Ulsan.
It’s right by Taehwagang National Garden (태화강 국가정원), down the alley next to the Starbucks.
Hours are 11:30 to 9 pm, with a break from 2:40 to 5 pm.
Last orders are 2 pm for lunch and 8 pm for dinner.
The break used to start at 3, so if you’re aiming for that in-between window, double-check before you go.

One thing for visitors from abroad: Google Maps is pretty unreliable for walking and transit directions in Korea.
I’d download Naver Map or KakaoMap instead. They’ll route you here properly.
How to park (read this first)
I’ll be honest, parking is the weak point here.
There’s no dedicated lot.
The first time I came I circled the alley for ages and ended up squeezing in somewhere, half-anxious the whole meal.
Most of the alley is resident-only parking, so don’t count on the street.
What I do now is just park at the public lot along Taehwagang National Garden.
It’s 500 won for the first 30 minutes, then 200 won per 10 minutes, capped at 10,000 won a day.
It’s a short walk to the restaurant and honestly the least stressful option.
On weekends or when the garden has an event, even that lot fills up,
so on busy days I park a little farther at the garden’s secondary lot and walk over.
Weekday lunchtime is usually fine.
If you’re driving, budget more time for parking than for the meal itself.
If you don’t have a car, it’s easy enough.
From Taehwagang Station you can grab a taxi for a short ride, and the Kakao T app makes hailing one simple even without much Korean.
And the bonus of this location is the garden right out front.
Even with a wait, a loop around the park kills the time nicely.
I remember the early days
I first came here a long time ago.
Back then there were maybe one or two other tables, a quiet little place.
It felt smaller than it does now, and the chairs were a bit uncomfortable, honestly.
The menu was short too, basically lasagna and a rice bowl.
Over a few visits the interior got a full refresh.
Now it’s a clean, cozy white-toned space with plants for accent.
The menu grew a lot, with pasta, lamb, seasonal lasagna,
and the cooking clearly leveled up.
It’s not a big room.
There’s a window bar, a few four-tops, a couple of two-tops.
A self-serve corner in the middle holds hot sauce, pickles, and napkins.
Dogs are welcome, so you’ll see plenty of people who’ve come off a garden walk with their pups.
Pet-friendly restaurants aren’t easy to find, so this is a nice touch.
I’ve heard the chef trained at ICIF in Italy, with some hands-on work there and a Michelin internship.
That tracks, because this doesn’t taste like your average neighborhood Western spot.
Make a reservation
It used to be walk-in-and-sit on a weekday.
Not anymore.
Weekends and holidays mean a wait, booked through CatchTable (a Korean reservation app),
and some days they only take walk-ins.
I reserve through CatchTable every time now.
With a booking you walk straight in, which is far less hassle.
If you’re a bigger group or coming on a weekend, a reservation is basically a must.
The app is mostly in Korean, but it’s manageable, and you can also just call ahead.
Small tip: ordering a set gets you roughly 10% off the à la carte prices.
For two or more people, the set is the better deal.
A quick word on paying and ordering, since people ask.
Like almost everywhere in Korea, cards work fine here, including international ones, so you don’t need cash.
There’s no tipping culture, so please don’t add a tip. It’ll just confuse the staff.
And don’t stress about the language. English is limited, but the staff are warm, sometimes a little English goes through, and worst case you point at the menu and hold up fingers. That’s all it takes.
What I’ve eaten
5F ragu lasagna (the signature)
If it’s your first time, get this.
Five layers of pasta sheets stacked with rich ragu, bechamel, and cheese.
The meat comes in good chunky bits,
and the sauce soaks into the pasta so well you end up spooning it up.
Tomato-sauce people will love it without question.
Cream lasagna
On days when ragu feels too heavy, I go for the cream lasagna (크림 라자냐).
It leans on mushroom aroma and mashed potato for softness,
and the cheese smell hits the moment it lands.
It’s a thick, creamy style, a different mood from the ragu.
Plenty of people actually prefer this over the tomato one.
Arancini
Honestly, I come back for the arancini (아란치니) as much as the lasagna.
Crisp outside, with kimchi fried rice and mozzarella inside.
You have to pile on the spinach cream sauce underneath to get the full effect.
The combo sounds odd at first, but one bite and your eyes go wide.
Even rice lovers will be into it.
Oven Napolitan
This one I underestimated.
I avoided it for ages, half-expecting ketchup pasta.
It’s a baked short pasta with ragu, sausage, and egg, more of a Japanese-Italian Napolitan (오븐 나폴리탄),
and it’s quietly delicious.
A touch sweet, a hit with older diners, and one of my friends swore it was the best thing on the table.
Guanciale carbonara
A common dish, so I ordered it with low expectations,
and the sauce turned out genuinely good, glossy and thick.
Not heavy at all, easy to finish.
If you’re adding a pasta, this is the one I’d point to.
Sides and the rest
The eggplant ragu rice (가지 라구라이스) pairs fried eggplant with ragu and garlic rice.
Even eggplant skeptics tend to clear the plate because it’s fried so crisp.
The calamari oil pasta (깔라마리 오일파스타) has chewy squid and a nice garlicky lift.
The caprese salad (카프레제 샐러드) resets your palate when things get rich.
I love it, so I add it almost every visit.
There’s also a carrot soup (5F 당근스프) that surprises people.
Creamy with a gentle sweetness, the kind that wins over even carrot-haters.
In the winter season they bring out lamb steak (양갈비 스테이크), French rack with a mushroom sour-cream sauce.
The seasoning and the cook on it were spot on.
Seasonal lasagnas rotate through too, like shrimp basil, truffle, or lobster, so it’s worth checking what’s on when you visit.
The honest downsides
I won’t just list the good parts.
First, the parking I already mentioned.
It comes with the location, so just go in mentally prepared.
Second, the price.
As a longtime regular, I’ve watched the menu creep up over the years.
The bread that used to come free now costs extra,
and portions aren’t huge, so big eaters will order more.
Still, given the quality and the room, it feels fair enough.
Third, the turnover.
With so few tables, you may wait for one to open up.
And there’s a matter of taste: the sauces run slightly sweet across the board,
so if you’re after strictly traditional Italian, it might read differently to you.
In summer, with the door open, I’ve had the odd little bug wander in.
Nothing that ruined the meal, but worth knowing.
So, would I go back?
Yes, every time lasagna calls in Ulsan, I end up here.
Proper lasagna spots are rare in this city,
and the signature ragu lasagna and arancini alone are reason enough to return.
They even made the 2026 Blue Ribbon list.
It works for dates, family meals, even with a dog,
and the walk into Taehwagang National Garden afterward is the best part of the routine.
Sort out parking and a reservation in advance and it’s hard to go wrong.
I’ll be back.
Getting there
25 Singi 4-gil, Jung-gu, Ulsan, right across from Taehwagang National Garden.
It’s a short taxi ride from Taehwagang Station,
and once you turn down the alley beside the Starbucks the orange-accented storefront is easy to spot.
If you’re driving, park at the Taehwagang National Garden public lot and walk over.
