What are the best surviving Roman sites in Asia Minor?

I've seen Ephesus and Aspendos suggested (along with an indication that there is at least one interesting city in Tunisia if I want to go to that end of the empire instead: Leptis Magna is the great site in that part of the world but it seems likely to be quite a while before contemporary geopolitics clear up enough for a visit); aside from the amazing cistern I was surprised how little Constantinople was left in Istanbul.
