It really depends on what characters you want to see and where you are going to be. From your signature picture it looks like you have two little girls so you might want to consider one of the princess meals. Breakfast at Cinderalla's castle in the MK, breakfast, lunch or dinner at the Norway restaurant in Epcot or 1900 Park Fare dinner at the GF.
Some of our other favorites in the past have been 'Ohana character breakfast (Lilo, Stitch, Mickey), Liberty Tree Tavern dinner (Mickey, Minnie, etc.) and Garden Grill dinner at Epcot (Farmer Mickey, Chip & Dale). The Playhouse Disney character meals at MGM seem to get fairly good reviews and we are checking it out for our next trip.
