We just returned from our trip, so here is my promised review. We arrived right at our PS time and were seated within 5 minutes. Our server was very attentive and we had more than we could possibly eat. It is served "family style": scrambled eggs (a little runny), large sausage links, bacon, biscuits, pineapple bread, a small bowl of fresh fruit, wonderful fried potatoes, Mickey shaped waffles and orange juice. We asked for more bacon and potatoes and they brought us plenty!
We were seated in a corner, which was nice for the outside view, but seemed like we had to wait a bit for any characters, maybe 20 min. But they all came around (Mickey, Chip, Dale and Goofy) shortly after that (Goofy stopped by twice). They didn't seem rushed to leave our table, so we got plenty of good pictures. They called all the kids in for a parade and gave them all marracas and they marched around the room. Not quite the conga line but still fun for the kids. We didn't feel rushed at any point, and we were there around 10:45.
I thought it was very expensive, around $90 with tip for 2 adults, 3 kids (13, 9 and 6) but it was comparable to any character meal, so this was not a surprise.
Overall, it was good experience, but probably not one we'd do again (only because we would rather do something we haven't already done). I would have preferred a buffet but Chef Mickey was already booked up and only had a 7 am PS available when we called. Several friends of mine said they would do Ohana again, over Chef Mickey: same basic characters, all you can eat, but less people and more interaction with characters. :sohappy:
