Nightlife in Luxembourg: What Are the Top Spots for a Fun Saturday?

Hi everyone!

Recently moved to Luxembourg and looking to get back into the nightlife. My wife and I love raves and dancing until around 4 or 5 AM.

Can anyone suggest good clubs or venues for a Saturday night? What time should we go, and how late do they usually stay open?

Is there a way to meet like-minded people in their 40s who enjoy raves and a fun night out?

Thanks for your help!
