Private venue for club gatherings

I'm not sure about the club door. On the one hand, it would be the easiest solution. On the other hand the lot in question is a 20x30 with a very narrow strip only in front of it. It also has bowling lanes, so during bowling hours (if lounge or bar), up to nine sims in ill-fitting bowling outfits would stand outside, possibly causing lag from constantly trying to reach the lanes. Moving the venue over to the empty 40x30 in the neighborhood would put it right next to a pirate ship playground, what would completely ruin the aesthetic.

The never opening Retail lot sounds intriguing! Do Retail lots allow for club gatherings?
