@Vibama Could you please try placing a couple of the buildings in a new save in Sunset Valley? If your sims can't enter them, please list the buildings, and I'll try in my game.
@Vibama I placed Banzai Lounge, The Grind, and Waylon's Haunt in a new Sunset Valley, along with the movie studio, and my sims had no trouble visiting any of them, other than having to bribe the bouncer at Banzai. So I'm not sure why yours couldn't visit. Have you double-checked that the venues are open? They all have different hours of operation, which you should be able to see if you hover over a grayed-out "Visit..." option.
@Vibama Try repairing the game in Origin: open your game library, right-click on the Sims 3 icon, and select Repair.
If that doesn't help, I can take a look at your save if you want. Upload the folder in ...The Sims 3 > Saves to a free filesharing site, and either link it here or send me a PM with the link.
