@elulu8, about Dinning Out GP, certainly get it if you are really interested with restaurants and food. I know @SheriGR loves running her restaurants in the game! ๐ However, I have heard from several people that if you want your Sim to just dine their with friends, or family, or on a date, that it isn't working as it used to. ๐ I haven't played a household in a while that has gone out to eat at a restaurant, so I can't say for certain. I can test it and see. Some of these bugs had been fixed before, but then again we just had several new patches so I'm not sure. ๐ค
That said, if the Dining Out GP is on sale, then this would be a better time to get it. I might be wrong about the bugs , or else they might get fixed, and in the meantime you can still play the restaurant owner aspect of the pack! ๐
You had mentioned that you thought it would be great to have so your Sims didn't have to cook in order to eat. To be honest, going out to eat takes a lot of your Sims' time, so even if everything is working as it should, just remember that , and maybe save eating out for special occasions, like Love Day (Season) or an engagement, etc. If you want your Sims to go out for a quick bite , City Living can't be beat! ๐ฅณ My Sims are always popping over to San Myshuno to eat at the carts at the festivals. And because eating at festivals doesn't take as long as dining in a restaurant, I find the festival food satisfies hunger much better! ๐ ( Just beware that you Sims can gain a lot of weight if they eat too much so either get them on that treadmill, or else get the Cool Kitchen Stuff pack and have them eat the ice-cream flavor called "Taste of Diet" that makes them loose weight while filling their hunger bar! ๐) Anyway, the festivals that come with City Living are why I haven't had any Sims dine in a restaurant in quite a while! ๐
As for building in City Living, just know that apartments can't be altered in the way houses can. Many people were expecting apartments to be able to be remodeled more than they turned out to be.๐คจ Some penthouses are more forgiving, and the Old Salt House that several people have mentioned is completely coustomizable, but then again the Old Salt House isn't' an apartment at all, as it is a house, just like its title says! ๐
