Bangi-dong izakaya open till 5am: salt-grilled mackerel at Sangkai

Why we chose Sangkai Bangi Branch in the Bangi-dong restaurant alley

On a day my friend and I finally synced schedules to meet near Jamsil, we wanted good snacks with a light drink, so we headed to the Bangi-dong restaurant alley. The moment evening hit, the whole alley was buzzing with its signature lively, chaotic energy.

Scanning through the countless options, right in the middle of the main alley we spotted an izakaya that caught our eye with its soft lighting and calm, upscale mood. The moment we opened the door, a cozy, sentimental atmosphere unfolded, so different from the noise outside — perfect for catching up quietly over drinks. Here's my honest review of a place on the Bangi-dong main street that nails both mood and flavor.

Where we stopped was izakaya Sangkai, taking up a spacious 2nd and 3rd floor above a lively sashimi restaurant on the ground floor. Drawn in by the clean signage visible from afar and the cozy orange glow spilling from the 2nd-floor windows, we climbed the stairs. The moment we opened the door at the top, a staff member greeted us with a bright, friendly smile.

Sangkai Bangi seats and hours: window tables, 3rd-floor rooms, open until 5am

When told to sit wherever was comfortable, we didn't hesitate — we claimed a window seat overlooking the alley below.

Looking around after sitting down, I noticed partitions carefully installed between the tables, letting you enjoy the lively main-street vibe while still keeping a private, cozy feel.

Upstairs on the 3rd floor, there were plenty of private rooms for group gatherings, company dinners, or just a quieter round of drinks.

The place runs comfortably from 4pm to 5am the next day, and apparently from 8pm to around 3am it's so packed you can barely find a seat. It made total sense why this place is such a buzzworthy spot in the Bangi-dong alley — the atmosphere alone proved it before we'd even opened the menu. With the lively alley as our backdrop, we got down to checking out the signature dishes.

The complimentary octopus salad and ordering by tablet kiosk

Before we even picked a menu item, the staff brought out a neat plate of octopus salad as a complimentary starter. One bite in, the octopus was surprisingly tender, not chewy at all, and the crisp fresh vegetables paired perfectly with the tangy dressing, instantly whetting our appetite. Even the free starter passed with flying colors.

Savoring that umami, we started browsing the menu on the tablet kiosk at our table. From sashimi to nabe (hot pot), stir-fries, and fried dishes, the variety was so dazzling it was almost dizzying. After some serious deliberation with my friend, we picked three can't-go-wrong dishes.

What we ordered at Sangkai Bangi and what it cost

• Lemon cream shrimp ₩19,500 — crispy batter with a tangy-sweet sauce
• Scallop butter salad ₩16,500 — rich buttery flavor
• Grilled mackerel with salt ₩19,500 — the classic izakaya grilled dish
• Baguette 2pcs ₩3,000 — added to dip in the cream sauce

Part of me wanted to fill the table with steaming nabe and skewers too, but to make sure we finished everything between the two of us, we saved those cravings for next time. Just as we'd finished ordering and were about to relax, my friend, still scrolling the menu screen, tapped my arm excitedly — there was a baguette add-on in the sides section, and she was sure dipping fresh bread into the creamy, tangy lemon cream shrimp sauce would be the perfect combo.

The moment I heard it, I thought "can't pass this up!" and added the baguette, 2 pieces for ₩3,000, without hesitation. Thanks to my food-savvy friend's instinct to scrape up every last drop of sauce, our table setup suddenly felt so much more complete.

With ordering done, all that was left was to make small talk while excitedly waiting for the chef upstairs on the 3rd floor to work their magic and send the dishes up.

Scallop butter salad, 16,500 won: how do the butter-grilled scallops taste?

Not long after, the scallop butter salad and lemon cream shrimp arrived looking so gorgeous my mouth watered instantly. The plating was so neat and pretty I found myself snapping photos before even picking up my chopsticks.

The first thing I reached for was the scallop butter salad. A generous serving of fresh salad sat on one side of the dish, drizzled appetizingly with balsamic dressing, so I tried a bite of that first.

The tangy, subtly sweet dressing combined with the crisp, fresh vegetables woke up my palate in the best way.

Next to it, the butter-grilled scallops caught my eye with their thick, round shape. The moment it hit my mouth, it practically melted, while the rich, savory butter flavor spread throughout — an absolutely perfect first dish.

Lemon cream shrimp, 19,500 won with a baguette add-on: about 15 shrimp

Next, my chopsticks moved to the show-stopping lemon cream shrimp. Fresh salad was mounded in the center of the plate, ringed by about 15 large fried shrimp arranged in a circle. The lemon cream sauce generously poured over the shrimp looked mouthwatering just to look at.

Picking up one plump shrimp and savoring it slowly, the crispy exterior and springy interior were fantastic, and the creamy, tangy-sweet sauce cut through any greasiness from frying, creating a truly wonderful balance. And this is where the baguette my friend added really proved its worth.

Piling springy shrimp and plenty of cream sauce onto the golden-toasted baguette and taking a bite,

the tangy-sweet flavor soaked moist into the crispy bread between bites — the definite 'kick' of the day, pure deliciousness itself.

Salt-grilled mackerel, 19,500 won: easy eating with no fine bones

Just as we were lost in the charm of the fried dish and the salad, the grilled mackerel with salt, worthy of being called today's main dish, arrived in impressive form. A mackerel large enough to nearly fill the big plate came out grilled to a beautiful golden brown. The delicate scoring cut so it would cook evenly through showed the kitchen's skill at a glance. Spicy fresh wasabi and soy sauce for dipping were neatly set alongside.

Excitedly, I picked up my chopsticks and pulled off a generous chunk to taste it plain first. The salt seasoning was just right, not overdone, so it tasted perfect even without dipping in soy sauce, and the thick, flaky mackerel filled my mouth, bursting with its signature clean, deep flavor.

Especially the smoky, crisply grilled skin and the bottom section were an absolute treat. And with almost no small bones — just a large central bone — it was easy to eat without fuss while drinking, which I really appreciated.

Dipping small bits into soy sauce with a touch of wasabi, my friend and I soon forgot to talk, focused entirely on devouring it with nothing but sounds of satisfaction. By the time we were pleasantly full, all that remained on the plate was the bare skeleton of what had been a huge mackerel, and we both burst out laughing.

After finishing even the last dish completely, we both had that satisfied, happy fullness that brings a smile. We promised each other to come back during peak hours next time and drink leisurely late into the night, then saved it as a regular-spot candidate on Naver Place and left in a great mood.
