Ask him where are his Hyungs...
I hope you're not mad at me for answering stupid stuff everytimes

A,B and C
And possibly even try and ask if he wanted to leave the club with me /shot

I would just stare at him.
Unless I was crazy that night, then I guess I'll spark a conversation.

I cant see anything -or is this an answer in the comment section -because If i spotted Taemin at a Night Club -Id play it cool and ask for Dance off :P
