Advice for bachelor party in Milan

At the end of September this year, Sept 27th to be exact, I am going to Italy for my best friends wedding. The bachelor party will be in Milan, and it is up to me to plan it. I wanted to reach out to see if anyone who is from there or has visited might have some insight on what would be memorable and fun to do for a bachelor party while in Milan. Any restaurant recommendations, night club recommendations, events that might be going on, things like that. I have to plan things for the entire day and I want to make sure it's the most memorable day ever (aside from the wedding of course). Thank you for taking the time to read this and if you have any insight, I can't wait to hear it!
