I have not been to a club night or otherwise in over 25 years. It's just not my thing. But I am curious what is the difference between a top table and a regular table? What even goes on at a regular table?
This seems very strange, why on earth would you pay that much to listen to music and who are you trying to impress? Is there some implicit assumption that you can meet otherwise unavailable women / men there? That seems extremely unlikely as well.
At these venues you aren't paying for the table per se... these are generally minimum spend amounts for drink/food (pre gratuity).
For ticketed events, table reso also usually includes admission & line bypass for x guests.
