I had a similar experience back in Seoul, but the vibe was way more relaxed at 홍대셔츠룸. Way less pushy, and the girls actually took time to chat a bit before getting into anything. Not saying it's cheap, but at least you feel like you're not just a walking wallet. Way better atmosphere than some of the other places I've ended up in by accident.
Had a similar experience once—paid for a private room, ended up with just an awkward chat and some half-hearted moves. Sometimes the vibe just falls flat no matter the hype.
