Seven themed private rooms, each named after a musician, with a catalogue of 80,000-plus songs and an hourly per-person rate that stays cheap for a big group.
Tuesday night karaoke at a sports bar by the F1 track, with no limits on song choice.
Open-stage karaoke in a British pub where the room sings along to the big choruses.
Six soundproof booths you can book for just 30 minutes, with costume props and a photobooth, so it works for two people on a whim.
