It's reasonable to take precautions, but deliberately misleading someone regarding your beliefs just feels like a bad choice, at least for a first date. If a long-time partner said they were into astrology, that would be different because there would already be something worth preserving.

I'm not sure about the restaurant thing, though if it wasn't really out of the way then I suppose it would be reasonable. But yeah, also cishet man so I am only stating my position/experience and not claiming it as absolute truth.
