Does it have to be breakfast? A nice choice might be to do a late lunch (say 2 p.m. or so to avoid the busiest time) at Garden Grill at EPCOT. Pluto is definitely there, along with Mickey, Minnie, Chip & Dale, and I think Goofy also. What's great about Garden Grill is that, unlike some of the other character meals, the characters seem to spend <I>a lot</I> of time with each person, children and adults. They keep coming around again and again throughout your meal, interacting with you. If you are unable to get PS or a ressie, just show up and you might still get in.
