Looking to find out what amount of space would make a decent size Billiards and Sports Bar. Looking to have about 8 pool tables 2 snooker tables a sports lounge and 75 person restaurant section.

Let's think about this snooker tables need 4 metres by three metres and pool table much the same so 120 square metres a restaurant needs 3 metre per person plus bar and cooking at least 300 square metres and your lounge say 100 square metres so 500 square metres. That's 25 metres by 20 metres or 80 feet by 60 feet

As a 'feet' measuring American, all I can say to 80 x 60 is something didn't compute in there somewhere. Way too small.
