Ephesus is good for a day trip, there is also the shine to the Virgin Mary close by and some of the villages in the area are lovely and can find excellent local food.

Closer to Cappadocia Konya may be worth a visit with some excellent Museums. It's the bastion of Islam so not great for nightlife or wine tasting.

Kusadasi is a bit of a tourist trap but the castle may be worth a visit.
