Mellow bar

4.9(45 reviews)$$$$

Tucked along Soi Rim Kong in Nong Khai, Mellow Bar draws a loyal crowd with its laid-back atmosphere and consistently well-received experience. Sitting in a quieter corner of the region, it offers a welcome alternative to busier tourist strips, with a mid-range price point that keeps it accessible without feeling budget. The bar leans into its name — the vibe here is unhurried and sociable, making it a solid choice for travellers looking to wind down after a day of exploring the Mekong riverside area. The setting suits both solo drinkers and small groups, and the crowd tends to reflect a mix of locals and visitors who have sought the place out rather than stumbled upon it. Good to know: Mellow Bar is closed on Mondays and Thursdays, with weekend doors opening earlier at 17:30 and weeknight sessions kicking off at 19:00. Last entry is midnight across all open days, so it suits an evening out rather than a late-night session. Given the address on Soi Rim Kong, it is worth checking the location on a map in advance as the soi can be tricky to find for first-time visitors. No website is listed, so confirming hours directly before visiting is advisable.

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.
