We were disappointed. It was the worst meal of our trip (except for fast food and our character meal). But it wasn't bad, it was just we'd heard it was excellent and it was only good. Plus, the buffet doesn't lend itself to exceptional dining and we really had to go out of our way to go here - we were staying at the BW. I thought the desserts in particular were overrated. Given the build up on Zebra Domes, I was expecting them to be better than they were.
The soups are really excellent. I don't think the soups were overrated at all.
(BTW, for comparison, we ate our other meals at Biergarten (we were starving so that probably helped it taste really good), Spoodles, Narcoosees, Marrakesh, Teppanyaki, Kona Cafe, Le Cellier (which we all thought was excellent)
