You may want to base your choice on the characters you want to meet as each restaurant has a slightly different mix.
We're trying Chef Mickey's for the first time this trip as my nieces and nephews want to meet Mickey himself and CM's is one of the few breakfasts where he presides.
We've previously enjoyed all the other CBs we've been to, including H&Vine, CPalace, 1900 PF, GGrill. They were all good, although I didn't like the GGrill as much as the others.
