We drive too and always eat at Chef Mickeys for breakfast on checkout morning. The food is good, & its fun to watch the monorail come in and out of the CR (depending on where your table is of course). Normally there is Mickey, Minnie, Pluto, Chip and Dale who come around to the tables while Goofy stays up near the entrance.
We went to Crystal Palace on our last trip which was also very good. Piglet stayed near the door while Pooh, Eeyore, & Tigger came to the tables. Ohana is popular too, as are many others. I think it all boils down to what characters you want to meet, and then you go from there.
