Last year, we (me, DH, 5 year old DD, & 3 year old DS) did the following buffets:
Boma Dinner at the AKL
Very nice restaurant! And the AKL is amazing. We got there early so that we could walk around & see the animals. Yes, the food on the buffet is "exotic", but I found plenty to eat. And there are plenty of choices for children as well. The desserts (zebra domes!!) were the best part, and we'd probably go back just for the desserts! LOL! Boma was the "perfect" ending to our AK day. This year, we're trying to try some new restaurants, so had not included Boma on our list. However, after reading everyone's reviews here & remembering how much we liked it, I may have to work Boma back into our plans!
Chef Mickey's Breakfast at CR
I thought it was fine - typical breakfast food (LOVED the Mickey waffles). The food wasn't extraordinarily great or anything, but the buffet was plentiful, food was kept warm, & there was (I thought) a nice variety. Atmosphere was fun & lively & loud - napkin twirling, the monorail running through the resort, cheerful music, etc. However, the morning we were there, the character interaction was very rushed (Mickey Mouse was the worst). DH, for some reason, was less than impressed w/ this restaurant (both the food & the characters) & doesn't want to go back this year...

I, however, would go back. All in all, I think it's a very nice "Disney experience" type meal - both in the location & in the traditional characters.
Crystal Palace Lunch at MK
We had one 1 of the first lunch reservations, and still had to wait 30-45 minutes for a table. The line at the buffet was very long. But, even w/ those 2 things, this was our very favorite buffet! The food choices were wonderful & varied & delicious!! (I got some kind of orange vinegarette salad dressing that was amazing!) And the restaurant was so pretty! And the characters were great as well. We did have to wait quite a bit on Pooh (for some reason, he kept "missing" our side of the restaurant), but he was terrific when he finally made it to our table. The kids went on a parade w/ Tigger. We could see the castle from our table. And, even though the restaurant was crowded, we never felt rushed. Crystal Palace is definitely on our "must do again" list!
Hollwood & Vine Dinner at MGM
We did this for our Fantasmic Dinner Package choice. Maybe because we were "buffeted out", but we weren't really impressed at all. Even though we had reservations, we had to wait quite a while before we were seated. The restaurant was very crowded & loud (but in a totally different way from Chef Mickey's) - the people at the table next to us might as well have been AT our table - that's how close some of the tables are. Typical dinner buffet items; the kids had plenty to eat. The decor was cute (retro Hollywood). DH didn't think the food was very good, and I have to agree w/ him. Of all the restaurants we ate at last year, this was probably our least favorite. This year, we're trying Mama Melrose's for our Fantasmic Dinner Package choice.
Trail's End Breakfast at FW
Typical breakfast buffet w/ the nice addition of Mickey waffles. Wonderful value! The restaurant wasn't at all crowded & the rustic atmosphere was really nice as well.
So, of the buffets we tried, Crystal Palace was our favorite, and Boma was our 2nd favorite. We would not do Hollywood & Vine again. We had the dining package, so I can't comment on the prices except we paid out of pocket for Trail's End, and I thought it was very reasonable.
I will say that, looking back, I think we did too many buffets. The restaurants, of course, stay busy, so it got tiresome having to get up & down from the table (w/ 2 small kids - this was often! LOL!) & then standing in lines at the buffets & juggle plates. This year, I only have Crystal Palace (lunch) & Donald's Breakfastauraus on our list - of course, I may be adding Boma!
