Opium Bar
Situated above Potong, a Michelin-starred restaurant on Soi Wanit 1 in Bangkok's Chinatown district, Opium Bar occupies a beautifully preserved old Chinese pharmacy building that gives the venue a character few bars in the city can match. The setting balances heritage and craft, drawing a loyal crowd of locals and travellers who appreciate bars with a story behind them. The cocktail programme is the main draw, with drinks that lean toward the unconventional — well-balanced, layered, and built around quality ingredients. Visitors who eat here also speak highly of the food, with dishes like wagyu fried rice and shrimp toast drawing particular praise. The intimate atmosphere suits couples and small groups looking for conversation and craft over volume, offering a clear contrast to Bangkok's louder nightlife options elsewhere in the city. Good to know: Reservations are required and come with a non-refundable deposit of THB 2,000 per person, so spontaneous visits are not an option — plan ahead. The bar's location slightly removed from the main Yaowarat Road bustle means it feels calmer than its Chinatown surroundings might suggest. Since opening hours are not publicly listed, confirming your booking details directly before visiting is advisable. The venue pairs well with a broader Chinatown evening, whether that includes street food, the night market, or nearby temples before heading up for drinks.

Visitor Reviews
While visiting World’s 50 Best Bars is not within my bucket list, no regrets patronising this place for the first time. Reservation was required for our visit with a non-refundable deposit of THB2000 in case of no-show. The deposit will be used to offset the final bill. Also, do note that there is a smart-casual dress code for this bar. Before my visit, I had confirmed with the bar via email (a prompt and professional reply which has set my expectation for the great service even before my arrival) that tailored chinos shorts are acceptable, just not beach shorts. Slippers or flip-flops are definitely not acceptable. The cocktails offered were quite interesting, especially the one that opted: World Champion - From Sip to Seed. Not too strong, elegantly presented that stimulates the senses of your taste buds. Other drinks on our table includes The Opium Oath (interestingly presented as well suited with its name), Pukka (with a BBQ squid to stimulate your sense of smell while taking a sip) and Hogmanay Tea (nothing fanciful). Of all the drinks ordered, I was glad that I opted for the World Champion drink. The drinks were served with refillable snacks as well. We also had the chance to order some food from the fine dining restaurant Potong; we ordered the Aromatic Dry-Aged Duck Leg Skewer (limited to 3 portions daily) and the Iberico Luo Buo Gao. Both were delicious, especially the turnip cake. This bar truly lives up to its reputation of being one of the World’s 50 Best Bars. Definitely lots of thoughts and effort poured into among those concoctions. Not to mention, the staff were friendly, knowledgeable and helpful as well! Note: The 2-person lift is interesting; but there may be a slight waiting time - else try going up or down the steep steps to experience the architecture of old buildings in Bangkok.
A hidden gem in Chinatown - the Opium Bar is bit apart from the noisy turmoil of the night market but definitely worth the extra steps! It's located in an old chinese pharmacy on top of the Potong Restaurant. The place has a lot of flair combining old and new elements. The service was extraordinary! Friendly, passionate and always on point. You could feel that they love what they are doing! And not only feel. You could taste it! The drinks were fantastic! Unique creations that orientate themselves on different parts of the world. Parts were the bar tenders travelled to and experienced the taste of. And this taste they pour into your glass! Absolute recommendation when you visit BKK and are looking for a good bar! Two hints to level expectations especially for european travellers like myself: 1. It's a high class bar with creative drinks and unique tasting experiences to enjoy the evening. If you just want to have something sweet to get hammered you are at the wrong place. 2. Expect drinks to be a bit more "lightweight" as you probably know them. This is due to the climate from my perspective. Otherwise the second drink would blow you straight out of your socks.
Overall, I had a great experience. The food was really impressive — the wagyu fried rice was rich and flavorful, and the shrimp toast was absolutely delicious. Both dishes were highlights of the night. The staff provided good service and were friendly and empathetic, which made the atmosphere enjoyable. However, it was sometimes difficult to get their attention — every time we needed something, we had to actively ask for service. If they were a bit more attentive, the experience would be even better. The cocktails were nicely crafted but felt a bit light on alcohol. If they were slightly stronger, they would be perfect.
Tips for Visiting Nightlife & Bars
Carry Your Passport or a Copy
Clubs and some bars check IDs strictly, especially in Bangkok's Thonglor, RCA, and Sukhumvit areas. A photo of your passport info page on your phone usually works, but carrying a laminated photocopy is safer.
Know the Closing Times
Legal closing time is 2 AM for most venues, though enforcement varies. In Bangkok's designated entertainment zones (RCA, Silom Soi 2/4, Khao San), some clubs stay open until 4 AM. Islands tend to be more relaxed about hours.
Buy Bucket Drinks Cautiously
Island bucket drinks (mixed spirits in a small bucket) are cheap and fun but notoriously strong and inconsistent. Stick to one, stay hydrated, and never leave your drink unattended at beach parties.
