Anything specific you're looking for? CBR as well as AoA and pop only have quick service options available. Basically they all have standard fare, nothing extraordinary.
Over at Riviera Resort, they have Primo Piatto, also quick service, but upgraded from standard with some better entree options, though similar pricing to the others.
Riviera also has Topolinos, which is a table service character breakfast. The food here is really good with good portion sizes. It's also somewhat all you can eat, except you have to order what you want up front, some get 2 entrees while some get 1 entree and add additional sides their entree didn't include. They also have Italian artist themed Mickey, Minnie, Donald and Daisy.
Beyond those restaurants, you could also take the skyliner over to the Crescent Lake area and walk the boardwalk for additional options. However, I think in order to use the skyliner before Epcot opens, you'll need to have a dining reservation.
