Klub25 Thonglor is an upscale gentlemen's lounge and premium KTV tucked on Soi Saeng Ngoen, a quiet lane off Thonglor. The format blends a main-room lounge with soundproof private karaoke suites, a cigar room, and VIP tables with bottle service, so one venue covers several modes of a Bangkok night out. Live house bands carry most evenings, with DJs filling gaps between sets across hip-hop, R&B, EDM, and lounge selections rather than a dedicated dance-floor programme.
Guests consistently rate the live bands among the strongest in the city, and the room holds a 4.6 average across 573 Google reviews. Local nightlife coverage has picked up on the same identity. Jetset Bangkok placed Klub25 Thonglor on its 2026 list of the six best gentlemen's clubs in Bangkok, flagging it at the top price tier, and The Thaiger included it in its 2025 top ten nightclubs ranking. It is one of the more polished club lounges in Thonglor, Bangkok for groups who want music, karaoke, and bottle culture in a single room.
You arrive any night from 8 PM, with valet or free parking handled at the door. The main lounge runs around a live band stage, so expect a seated, bottle-led room rather than a standing dance floor. Tables are the default unit of service: book a VIP table with bottle service, or take one of the private KTV rooms if your group wants to sing. The karaoke catalogues cover Thai, English, Chinese, Korean, and Japanese, which tells you who the room is built for.
Dress code is loose. The venue allows shorts and only suggests smart casual, so you are not turned away for arriving straight from dinner in Thonglor. A separate cigar lounge with premium cigars and fine spirits sits alongside the main room for guests who want a quieter corner. Last call is the one moving target: Google lists midnight closings, while the venue's own site and most third-party listings say 2 AM, so confirm by phone if you are planning a late arrival.
The live band programme is the headline draw and the reason most regulars keep coming back, with multiple house acts rotating through the week. Private KTV rooms are the second pillar, soundproofed and stocked with multilingual song catalogues across five languages so mixed groups of Thai, Chinese, Korean, Japanese, and English speakers can actually share a mic. VIP tables with bottle service anchor the floor around the stage, and a dedicated cigar lounge carries premium cigars paired with fine spirits for guests who want to step out of the music. VIP membership at Klub25 Thonglor layers on complimentary mixers for a full year, a personalised host, priority booking, and discounted bottles, which is how the venue rewards its frequent groups.
Klub25 Thonglor sits at 4 Soi Saeng Ngoen in Khlong Tan Nuea, Watthana, a short drive from the main Thonglor strip on Sukhumvit Soi 55. BTS Thong Lo is the closest station, and the venue offers valet and free parking on site, which matters on this side of Sukhumvit where street parking is tight after 9 PM.
