YMMV, but I actually think the sustainable fish dish they do is probably the best non-signature fish dish on property. I mean, I know that's a weird qualification, but it's quite nice. On the other side, their burger is great, their cobb salad may not be the Brown Derby's but I always found it pretty awesome, and their appetizer fish tacos are also quite yummy.
I also really enjoy their breakfast: there's a buffet if you like that, too, with some interesting stuff (like their sweet potato pancakes), but I prefer ala cart. They're also probably one of my favorite lunch spots, and the spot I almost always eat lunch at on MK days. Personally, they're one of my favorite non-signature restaurants, and definitely my favorite one in the Mk area.
