I haven't counted mine. The one thing that bugs me, however, is that Sulani and Del Sol Valley don't have any eateries! I did turn the park in Del Sol Valley into a restaurant I got from the Gallery. It's a beautiful, atmospheric Asian Food place. I call it the Red Dragon in my game.
Still haven't quite sorted out where to put a restaurant in Sulani. If there is one in Mt. Komorebi, I haven't found it.
I put three in Newcrest, along with several other lot types: Karaoke Bar, Nightclub/concert venue. This was set up to give my budding Rock Star places to hold concerts. Many of the venues I use are from the Gallery. I have built a few of my own, too.
I agree, too many lots are taken up by the same type of lot across the board. Since it's no big thing for our Sims to travel to another 'World' I don't have a problem removing yet another gym, bar, or museum to install something I need in my game.
