We really like this one. I tried for Chef Mickey's last time and was late in booking, ended up at Ohana's and couldn't have been happier.
We spent about 40 minutes - didn't feel rushed. We had a party of six (me, DH, DD(2), DS(3) and Grandma and Grandpa). Family style was a HUGE benefit with kids - as all us adults got to sit and enjoy the food and characters - without hopping up every two minutes for more food. I'd really recommend this as a choice to anyone travelling with kids too small to get their own food, or anyone who is physically challenged enough that a buffet is problematic (for instance, an elderly grandparent).
Its a short hop over to the MK, so its a great choice for a MK morning. Our PS was one of the first, and we were there before park opening.
The only complaint I've heard with family style is that sometimes the CMs are a little slow bringing food around (espcially if you are feeding teenage boys!). We didn't experience this personally, but you are giving control over to someone else.
