I'm from an Italian family. We always have a cake and there's ALWAYS a tray of cookies brought to each table. Sometimes even little pastries as well. For many years, there has been the custom of a "Viennese" table set up with an array of desserts. Sometimes an enormous display, sometimes not so big. Depends on how much money the bride wants to spend and also depends on the catering hall. There is still always the cake. I think the idea of a cookie table with goodies made by family is a wonderful custom and I would venture to say it's local.
