Let's see...
1) I changed the tiny park in downtown Del Sol Valley to a taco truck with outside seating. (It's also still sort of a small park, as it has benches, music and a small dance floor, and an outside chess table.) It's pretty great, if I do say so myself. Great for families, meeting new friends, or grabbing a bite after clubbing.
2) Sort of a pan-Asian restaurant, also in downtown Del Sol Valley. It serves mostly Chinese food, with some Vietnamese dishes. (It also served sushi until we got Snowy Escape, when I removed those options and created a full Japanese restaurant in Mount Komorebi.) I tend to use this for first dates or family special occasions.
3) A vegetarian restaurant called Thymes Gone By (yes, it's cheesy, don't judge me because I love it!) in the heart of Old Town Windenburg. It's right by the big fountain, I think in the building that used to be a dance club or something? If I had to choose, this is probably my favorite. I love to take big groups of family or friends here, especially for brunch.
4) A fancy seafood restaurant by the docks on the island in Windenburg. I tend to use this for first dates and anniversaries.
5) Technically it's a bakery, but I also have a bakery-cafe on the small lot on the island with inside and outside dining space.
6) In Brindleton Bay, I changed the bar into a more casual/family dining seafood restaurant with the less-fancy fish dishes.
7) In Newcrest, I took the Maxis-created lots that were added to our libraries (I'm pretty sure), for the high-end experimental restaurant (special occasions and celebrations), the Italian restaurant (mostly romantic evenings), and the restaurant that seemed to me like a trendy mid-range brunch place (friend brunches and networking meals), and tweaked the decor and menus slightly to fit my needs better.
8) In Oasis Springs, I have a diner that serves classic diner food, Tex-Mex dishes, doughnuts, and ice cream, basically. It's basically a social hub for Oasis Springs.
9) Again, not quite a restaurant, but I created a retail lot in Henford, just off the main square, that is a small grocery store, but also has a kitchen (blocked off by the counters with a cash register and a back door locked for customers) that has a small eat-in area inside and a picnic table outside, and customers have access to the retail cooler for precooked meals. I.e., it's meant to be a grocery/takeaway cafe with pub food.
10) In Willow Creek, I have a restaurant that is Southern/homestyle cooking in one of the buildings in the most expensive neighborhood that was originally a lounge or a bar, I think. The kind of place you would go with your family or friends right after church on Sunday, for those of you who are familiar with that sort of thing.
11) In San Myshuno, I turned the karaoke bar into a restaurant that is a mishmash of different cultural influences in the decor, menu, and attire. Basically, I put on the menu everything that that didn't have enough related dishes to make a full restaurant elsewhere. The downstairs is the main restaurant space, plus a hookah room; the upstairs has a coffee bar, a reading area, and a meeting space with a podium and seating. Basically, it's meant to replicate places I have seen in cities where I have lived that are part restaurant (often co-op/activist group-owned), part community meeting space, part library/resource center.
I think that's pretty much it. I would love to put a restaurant in Tartosa, but probably don't have space. Same goes for some of the other neighborhoods. If there were room, I would totally do a meat-only restaurant in Moonwood Mill and a plasma cafe in Forgotten Hollow. Maybe someday we'll get a big spooky world, and I can either do both or at least combine those ideas.
