Are you interested in just the fashion part of Versace or are you also interested in Gianni Versace? You can dine at the former Versace mansion in Miami and that might be a cool thing to do if youre that into them.
Am interested in both and would really love dinning over there. Do you know on how I can go about it?
You would have to get a reservation for dinner but the bar is always open for walk ups for drinks!
Is it an open bar or do you have to pay for it?
No you have to pay for drinks and if you wanted to stay in the hotel portion its around $750 per night. What you can do for free is take a photo on the steps where Gianni was murdered. 
Damn $750? That will not work for me but taking a photo at the steps that's something. It will mark a historical photo in my album
If you want to stick with a morbid trip to the sunshine state you could visit another famous haunted house built by industrialist Charles Deering! The estate is a public museum and hosts ghost tours!
Tell me more about it and I might consider visiting the area
Deering was what southerners call a "carpet bagger" a northern who moved down to a southern state to try to get in on the ground floor of a new business venture.  He built all sorts of things on the land he purchased and lived there until his death. His spoiled son Henry would later dig up native burial trying to find treasure, and you guest it, unleashed hauntings on the land!
Wow Thanks for the insight I will consider visiting the place soon
There is even a prehistoric burial mound on his estate! And you guessed it, him and his son dug up bones and skulls from the mound and tossed them out onto the coast! They were looking for Black Caesar's treasure.
