The cafe is the Gelataria Cafe Expresso. They have basic items like muffins, little boxes of cold cereal, toast, bagels, fruit, etc. I found it very pricey though. It cost almost $9 for 2 coffees and a muffin! The trattatoria has a breakfast buffet. It is $13.95 per adult. and are very good. You can also order ala carte. I think their coffee is the best on property.
There is a restaurant in citywalk, Pastamore, that serves some breakfast items. Last I read, before 8am your choices were very limited there. After 8, full breakfast's available.
Are you aware that both parks serve breakfast items at the bakeries just inside the entrances? They have a good breakfast sandwhich for about $5, fruit cups and all kinds of muffins, croissants (chocolate, mmm), big cookies

, etc. Pretty good coffee though.
Are you interested in off property choices? Barry knows where all the cheap breakfast places are!
