In short

B LAB Gangnam Station Main Branch is an unlimited cocktail bar on the 2nd floor of a building on Gangnam-daero 98-gil in Gangnam, Seoul. On a Tuesday evening, after pho, the writer came for round two, took a side floor seat with a backrest, and ordered butter popcorn, zero cola and a mango milk cocktail. With non-alcoholic drinks on the menu, B LAB works as a Gangnam Station bar even for a night when you are not drinking.

Hey everyone?!!?! It's Haley~~~ After (not really) meeting up with Sunnie for a tasty pho dinner, I was trying to figure out where to go for round two. A café felt a bit meh, and I was already stuffed, so after much deliberation I decided to head to B LAB, a place where you can get unlimited cocktails again for the first time in a while! Let me tell you about B LAB, a Gangnam Station bar that's great for sitting comfortably and chatting the night away.

Where is B LAB Gangnam Station, and what does unlimited include?

B LAB Gangnam Station Main Branch is an unlimited-drink bar on the 2nd floor of the building at 10 Gangnam-daero 98-gil. Once you turn in from the main Gangnam-daero street, you'll see the B LAB sign up above as you walk up. It's written super large so it wasn't hard to find at all haha. There's even a standing sign out front announcing unlimited drinks for ₩18,000 — this really is a Gangnam Station bar.

Cocktails, highballs, shots, tequila, whiskey, vodka, soju — all unlimited~~ But isn't a highball technically a cocktail too?? (whispers)

B LAB on a Tuesday night: why the floor seats are the comfiest

Here's what the interior of B LAB looks like. We went on a Tuesday so there were plenty of open tables and I could get clean shots of the space. If you come on a Thursday or Friday, every single seat is packed, so you won't get this relaxed vibe — this place is seriously popular lol.

The spot Sunnie and I love is the seated booth on the side! It has a backrest and is so comfortable it almost feels like a private room café haha. Sit down and start chatting and you won't even notice the time passing.

Photo zone, Han River ramyeon zone and board games at B LAB

On the way to the bathroom I snapped B LAB's photo zone and Han River ramyeon zone! There's a photo zone set up for pictures, and on the other side there are all kinds of board games ready to play. Every time I come I see groups of guys playing board games together lol.

Butter popcorn, and bringing your own food into B LAB

We also got an order of B LAB's butter popcorn (₩5,000). The portion is genuinely huge — you could come here and just eat this alone lol. They sell side dishes, but you can also bring in outside food, which makes B LAB a really easy, comfortable Gangnam Station bar to hang out at.

How QR ordering works at B LAB, with a KakaoTalk alert

You order from B LAB's menu using the QR code at each table, and once your drink is made you get a KakaoTalk message so you can go pick it up!

A Gangnam Station bar you can enjoy sober: zero cola and the mango milk cocktail

I had drinking commitments before and after, so I played it safe at B LAB with zero cola. It's not just about the alcohol — there are non-alcoholic cocktails and soft drinks like zero cola too, so it seems like a great spot to come use the space even if you're not drinking. I still got to try a variety of cocktails without any pressure to drink.

Lastly we ordered two glasses of what I think is the tastiest drink at B LAB, the mango milk cow, and wrapped things up. Next time I'll be back with Sunnie for zero cola and more chatting lol.
