What reviewers say
Strong song selection and A/C comfort at affordable base rates (500 baht/hour) appeal to karaoke enthusiasts; however, multiple reviews across languages document systematic overcharging (reaching 10,000+ baht bills), broken equipment left unrepaired, rude staff, and opaque pricing that varies by visit. The consistent pattern of billing confusion and undisclosed costs suggests customers should clarify all fees upfront before entering.
