Zest: Seoul Travel Guide

Why Zest matters right now

Zest is the bar Seoul’s drinks scene keeps pointing to. On Asia’s 50 Best Bars 2026 list it held the No. 2 spot for a third consecutive year, and it’s now been named Best Bar in Korea for a fourth straight year running. That’s not a fluke — it’s a bar that’s been consistently at the top of the regional conversation for half a decade.

What sets it apart is its zero-waste ethos. Rather than treating sustainability as a marketing line, Zest builds it into the actual craft: house-made sodas, house-distilled spirits, and citrus, herbs, and off-cuts that would normally hit the bin instead going into syrups, cordials, and garnishes. The signature is the Jeju Garibaldi, built on hallabong — the thick-skinned, sweet Jeju tangerine — reworked into a bar classic that tastes distinctly of Korea rather than a copy-paste of an Italian original.

Where to find it

Zest sits in Gangnam-gu, Seoul’s glossy southern business-and-nightlife district known for high-rise offices, luxury retail, and a dense cluster of the city’s most ambitious bars and restaurants. Gangnam rewards a bit of wandering after dark — this is a neighborhood where basement-level cocktail dens sit below unmarked doors.

Because exact address and access details can shift, confirm the current location and nearest subway exit on Zest’s official channels or a reliable booking platform before you go. Gangnam Station (Line 2) and Sinnonhyeon Station (Line 9) are the general anchors for this part of the district.

What to expect inside

Picture a bar built around precision rather than spectacle. The zero-waste approach means you’ll likely see bartenders working through house-made syrups and infusions rather than pre-batched, name-brand liqueurs off a shelf.

Expect a tasting-menu mentality applied to cocktails: drinks designed to showcase Korean ingredients — citrus, herbs, tea, fermented notes — filtered through classic technique. The Jeju Garibaldi is the drink to try first if it’s on the current list, since it captures the house style in one glass: bright, citrus-forward, and rooted in a specific place rather than generic.

Don’t expect a sprawling, loud room. Bars of this caliber in Seoul tend to run small, seated, and deliberately paced, so plan to stay for a couple of drinks rather than a quick one.

When to go

Given its ranking, Zest draws serious cocktail tourists alongside locals celebrating something worth toasting. Weeknights, especially earlier in the evening right after opening, are your best shot at a calmer room and unhurried service.

Weekend nights will be busiest, particularly after 9pm once dinner reservations across Gangnam let out. If you want conversation with your bartender rather than a shout across the counter, aim early.

How to visit like a local

Book ahead. A bar holding down a top-two regional ranking for three years running does not have walk-in space to spare on weekends, so treat a reservation as essential rather than optional.

• Reserve via the bar’s official page or a trusted platform, not a third-party reseller
• Arrive close to your booked time — small, high-craft bars often run tight seating turns
• Order by asking what’s seasonal; the zero-waste concept means ingredients shift with what’s fresh
• Tip is not expected Korean-style, but check if service is already included in your bill
• Dress code leans smart-casual, in keeping with Gangnam’s polished bar culture

The mistake visitors make here is treating it like a quick stop between other bars. Zest rewards slowing down — order two or three drinks, ask the bartender about the zero-waste process, and let the pacing be part of the experience rather than an obstacle to it.

Nearby to pair with the visit

Gangnam-gu is dense with things to do before or after your reservation. COEX Mall and its Starfield Library are a short trip away for daytime browsing, while the district’s restaurant scene ranges from casual Korean barbecue to some of Seoul’s most talked-about fine dining.

Since Zest’s own hours, exact address, and reservation policy can change, always double-check these directly with the bar or a current booking platform before finalizing plans — details for fast-rising, award-winning bars tend to shift as demand grows.
