For the most part, yes, you can split meals at
Disneyland. I've shared entrees with family members at many of the restaurants (Cafe Orleans, Carnation, RBT, Cove Bar, Alfresco Terrace) without a problem. The one exception is the Blue Bayou. They charge a split plate fee because each person will get their own starter (comes with all entrees) and sides. There have been some reports that if you tell the server you want to share a single meal (i.e., one starter and one set of sides), then they won't charge the split plate fee, but you need to check with your server to see if that's still true. Also, you cannot "share" at buffets/AYCTE, dining packages, and character meals (those charge per person).
