As far as I know, Cafe' Orleans is open for breakfast during peak attendance times only. I've been to Disneyland more times than I can count, and I've only seen it open for breakfast a few times!
I will just wait until the 60 day reservations are available for me, and then call to ask.
I would really like to do breakfast there during our trip. The beignets are calling my name. Loudly. And I think the family would eat breakfast there better than any other meal (more things they like at that time).
When we tried on 12/17 (Thursday) they were not open until 11:30 I believe. We ended up over at the River Belle Terrace and it was pretty good, great table out on the terrace, loved the view of everything and everybody.
