Apparently there was a restaurant named Three Cities of Spain that served this delectable cheesecake, which is how it got its name. But never mind. I think of this as Ruth Reichl's Cheesecake and that's all.
This is a thick, smooth, rich cheesecake with a sour cream topping that is very simple to make. It is also very satisfying and is best made for an occasion because you'll want lots of people around to help you eat it. Keep in mind that it needs to chill for six hours (or as long as overnight), so plan accordingly.
