How to register a "Social events" business?

Hi,
I have access to a commercial space that for urban planning reasons can’t be registered as cafe, bar or restaurant.
I would like to host monthly social events where people could meet and socialise and where I could, ideally, hire a licensed caterer to provide drinks and food to the guests.
The customers would pay a ticket upfront to attend the event and it would basically be a private event with no access to the general public.
I wonder if anyone has any idea on how this type of business could be registered?
Specifically, which code could be used?
(For example F501050 is the code for Bars, which can’t be registered at the address that I intend to use)

Thanks!
