1. Church. This has historically been the central element of European small-town life, and the church tower is still so often the literal high point of many small towns. You could also have a small cloister attached with some monks.
2. Recycling Center. Some cool machinery could be introduced here, with a scooper on tracks, conveyor belt, sorting machine. You could convert it to a factory, too.
3. Restaurant. Including the front dining room, and all the back operations: food storage, dishwashing station... but maybe the Pizza Corner took care of the restaurant for a while.
