We're big fans of the character meals at Tusker House. The buffet is arguably the best you'll find at a character meal, and we've had excellent interactions with the characters there every time we've gone. If I remember correctly, the most recent grouping we saw (2014) was Mickey, Goofy, Donald and Daisy. Breakfast is our meal of choice there, though we also did lunch, and enjoyed that as well.
Our next trip, we intend to try a breakfast character meal at Garden Grill in EPCOT. We haven't done breakfast there yet (they only recently started doing breakfast, I think?), but we had a really lovely character dinner there on our last trip (also 2014) - not a buffet, but a set menu that's brought to your table and is all-you-care-to-eat. The food was fresh and tasty and the characters (Chip, Dale, Mickey, Pluto) were lots of fun.
On that same trip, we also did breakfast at 1900 Park Fare. We'd had dinner there and liked the food better at dinner, but breakfast was decent, at least. We met Alice, Mary Poppins, Pooh, and Tigger. Pooh and Tigger were... less interested in our table than I'd have liked - they appeared to be approaching their break time and I guess really wanted to get off the restaurant floor. My son (5 1/2 on that trip) was a bit bummed. A pat on the head, a character autograph, and on to the next - not even a moment for a hug or a photo with those two. On the flip side, Alice and Mary Poppins were terrific, paying that extra bit of attention and chatting in perfect character with my little guy. I don't know that we'd do that meal again, but it was more positive than negative, overall.
While I tend to see a lot of people recommending them, I personally cannot really recommend the character meals at 'Ohana (breakfast), Crystal Palace (breakfast), or Chef Mickey's (multiple meals). At 'Ohana, we thought the food was pretty poor (hot food served cold, bacon nearly raw, in general our meal was just greasy and disappointing), and the characters were rushed almost to the point of rudeness - I barely had time to take a single photo before the character was on to the next table (and yes, my camera was ready in my hand as they approached). Our experience with Crystal Palace was all-around a mess - we had breakfast before park opening and our table was dirty, the food wasn't very fresh, and the characters were mobbed a few times by overeager kids - we actually had to ask a handler to have Tigger double back, because he totally skipped our table after one of those mobbings. (I felt bad for Tigger and pretty much understood how distraction could lead to a missed table, but the nephew we were traveling with was devastated that Tigger had passed him by.) At Chef Mickey's, the food was just not good at all... but the character interaction was great, so we did repeat that one a few times. We just can't stomach the food there anymore! Obviously, plenty of people go to these meals, and many do like them... so YMMV.
