Disagreeing is fine, posting mis-information is not. Not saying that you posted mis-information, just saying.
And I'll say it again..I have NEVER had ANYthing at Mimi's with gravy on it...unless you want to count the amazing hollandaise sauce they put on the eggs benedict.
I've eaten at Millie's a few times, it's good. It's standard American Fare, nothing fancy but nothing gross that I can recall. We did bfast there on the way to the parks when we stayed at the HoJo.
Another vote for Mimis or Mcds if we are in a rush which we often are. It is nice to sit in a relax at Mimis at least once during our stay though. If you have kids Mcds keeps things simple. If you are on holidays it is time to let your guard down a bit on what the kids eat. Ours eat fastfood about once a week? So it is nice during our stay to become fastfood junkies and know that we will burn it off walking all day. It is like the 4 hour body "cheat day" for the entire time we are there
