Samurai Cafe in Osaka reviews? Tourist trap or worth it?

Hey everyone, has anyone been to Samurai Cafe in Osaka? I'm seeing suspiciously good reviews on Google & TripAdvisor for what seems like a very small and honestly, tourist-trappy looking place.

Just trying to decide if this is a genuinely great experience or a waste of precious time in Osaka. Would love to hear from anyone who's actually been. Thanks!
