SIN Rooftop Bar Bangkok

4.9(996 reviews)

Featured in: Best Rooftop Bars in Bangkok

Perched on the rooftop of the Avani+ Riverside Bangkok Hotel on the Thon Buri side of the Chao Phraya, SIN delivers one of Bangkok's more striking riverside panoramas. Sitting 27 floors up, the bar looks out over the illuminated city skyline and the river below — a setting that draws particular praise from visitors for its romantic atmosphere after dark. Live DJ sets are a regular feature, giving the venue a club-like energy that sets it apart from more sedate rooftop bars around the city. The bar functions as both a cocktail bar and a dining spot, with visitors noting well-crafted drinks alongside light bites such as fresh juices and quality seafood. The service receives consistent, specific praise — multiple guests have called out individual staff members by name for attentive and genuinely warm hospitality. The atmosphere skews upscale but relaxed, drawing a mixed crowd of hotel guests, tourists, and locals. SIN opens daily at 5:00 PM, closing at 1:00 AM Sunday through Thursday and 2:00 AM on Fridays and Saturdays. Arriving before 7:00 PM is advisable for anyone wanting to catch the sunset and secure a good seat, as the space fills quickly during golden hour. Smart casual attire is the standard — leave beachwear at the hotel. The venue is accessible via BTS Skytrain to Krung Thon Buri station or directly by water taxi to the hotel's riverside pier.

Visitor Reviews

We had such a wonderful time at Sin Rooftop Bar. From the moment we arrived, Jae ,Gift, and Au took incredible care of us. They were consistently attentive, making sure we always had everything we needed. Even when we wanted to order things that weren’t on the menu, they helped us with so much kindness and a smile every time. The atmosphere was perfect , not crowded at all, which made the whole experience even more relaxing. The live DJ created such a great vibe, and we were lucky to enjoy an absolutely beautiful sunset from the rooftop. The place itself is stunning, and the service truly made the night unforgettable. Highly recommended! We’ll absolutely be coming back. ❤️

This rooftop is absolutely amazing! Out of all the rooftops in Bangkok, this one is my personal favorite. Even though it's on the 27th floor, the view of the river at night is breathtaking and so romantic. The music was incredible, and the DJ was a real pro. The cocktails were delicious, and the staff provided excellent service. Entry is free. We ordered a cocktail each, and the total was around 1400 THB. Given the great atmosphere and the vibe, it’s definitely worth it! My only wish is that more people would get up and dance because the music is just too good. I will definitely be back!

I was staying at the hotel for 3 nights and stopped by one evening for a drink and light bite to eat. SIN is located in the Avani+ Riverside Bangkok Hotel. I had the fresh lime juice and Gillardeau Oysters classic mignonette, lemon wedge (6 pieces). Very nice. I would suggest making a reservation if you can. I luckily managed to grab the last bar seat as a walk-in. The setting is stunning as are the views. Really good music. Excellent service and friendly staff. Pricey but worth a treat.

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.
