Chef Mickey's - awful food and pandemonium for breakfast! I think we'll give it another try when our YDD is a little older, or if we are staying at BLT more. But for now, it's not in rotation.
'Ohana breakfast - same! The character interaction was good, but it was noisy and the food was only marginally better than CM.
Mickey's Backyard BBQ - I realize you're there for the show (for the kids) but the food - ugh! I felt like I was back in my elementary school cafeteria, and not in a good way! And also, LOUD.
That said, we are generally pleasantly surprised when we eat at WDW. Then again, when dining with little kids, we are probably the ones making it a less pleasant experience. Our 5yo's favorites include CRT and BOG dinner. Last time at BOG (we've been once each trip since it opened, I think), the food was way too salty. But previous visits, the food was very good. CRT, I feel, had stepped up its game and the food seemed better in 2016 than it had been previously.
