An Invitation to a club in the red light district

You pull a small piece of paper out the box. An invitation to "Caesars lounge". The name doesnt tell you anything, but a quick google search confirms that its a pretty private club in the red light district of town. You dont find any pictures of the inside of the club, only some from the front entry.
Besides that, you fina a note and some clothes in the box. The note is in cursive handwriting.

Wear this. Friday, 9pm. Second floor, third door to the right.

You lay the note aside and look at the clothes. An expensive looking suit, new shoes, a shirt. Whoever send you this package didnt shy away from spending a bit. You try it on, it fits perfectly.
Still, you have no idea who would invite you to this club, or what it would be like on the inside, but before you know it, Friday comes, and you find yourself getting a taxi to the club.

You look up aat the facade of Caesars lounge. Pillars decorate the entry, which is guearded by two doorman. Invitation in hand, you go up the steps that öead to the door.
