Bar % out of padel center revenue

To all padel business owners!

I know this is a tricky one, but I am looking to understand what's the bar average % of revenue out of the total revenue of a padel center business. This will for sure depend on so many factors like the offer of the bar and the population in the area, but I am building up my business case and want to land something that is a good base to start working with in terms of numbers or %/ ratios.

Thanks for your help!
