We were there last week and came back disappointed. On our last trip to WDW, we stayed at WL so ate there twice and loved both the food and antics. The kids and DH requested a return to that restaurant with the ketchup thing, so I made ADRs this time.
I was disappointed in both quality and atmosphere this time around. Maybe part of it was because we were staying at the Polynesian on this trip and so had to make a special trip on the boat over there (not really that hard when you're at MK anyway, which is what we were), or maybe it was just an off night. Our server was very sweet but not that much was going on. We were seated right in the main dining room in the middle actually. Ketchup was called for as on the past, and the kids had a pony race (although my boys decided they were too old for it), and the servers all clomp their trays on the floor, but those things alone were not worth the time and effort to me.
Maybe if I hadn't been there before, I wouldn't have cared so much, but it was just mediocre really. That said, a large group could have fun here although if I had to do a "fun" silly atmosphere meal with a large group, I'd prefer 'Ohana.
