I've only been once, in 2016 before breakfast prices shot up and we were on QS dining plan anyway. It still wasn't worth it, IMO. The food was 'meh', and the over-hyped atmosphere? I later saw it described on here as looking like they'd decorated the school cafeteria for a Beauty and the Beast themed prom. That's perfect. I mean...it's cute, but it's not THAT cute.
Last time I ate breakfast in Magic Kingdom, my friend and I grabbed breakfast wraps at Main St. Bakery and then went up and sat on a bench out front of the train station overlooking Town Square. We were all by ourselves, munching on our wraps and enjoying the view down Main Street. And then Mary Poppins came up there and hung out with us for a little while! Best breakfast in MK I've had yet.
