you'll find that lot in the new neighbourhood. it's in the description for it also. if I'm not mistaken, you can also build your own communal lot with one of the tables on it.
I had a sim that endered one. the old man is living with him, and entered too. the funny thing is that he won over a chef and a bartender
you can also make siong contests with a DJ-booth, though they have to be four people to do it.
