BOG is a MUST if you are a Beauty & the Beast fan. It's really an experience for any fan of that film. I also enjoy Tony's. It get a bad rap sometimes, but I like their meatball apps, salad, and lack of characters (so many of the MK table places are running over with them, that sometimes it's nice to catch a break with some decent food). Liberty Tree is
not my jam, but plenty of other people seem to enjoy it. Plaza is so hit or miss that I would rather skip it and hit up somewhere QS (the food is almost the same anyway, and right now you don't get the view that usually goes with the ADR there).
SciFi has great ambiance and decent burgers & shakes. The food isn't going to knock your socks off, but I would suggest everyone go at least once. We ate at MM for the first time in August and was surprised by the food. Not the same caliber as the places in the Italy pavilion, but good Italian and a decent wine selection. Brown Derby is also delish, just to throw that hat in the ring. And you can eat at the lounge outside without a ADR and get the famous Cobb Salad & Grapefruit cake. Also, the marg flight is basically just 3 full-size margaritas. #winning It's a sentimental favorite for my family.
I highly recommend Biergarten, Via Napoli, Spice Road Table (it's gotten mixed reviews, but we've enjoyed the view & garlic shrimp here as well as the sangrias), and the Tutto Gusto Wine Cellar is an awesome little spot that we have always been able to walk into and the atmosphere and tapas are delightful. My beef with Garden View is that it seems like Such A Hike back to WS Lagoon at the end of a long day of touring to watch Illuminations. Boo. Maybe for lunch after a Sorin FP? You could also skip over to the Boardwalk area and check out Flying fish, Yachtsman Steakhouse, the new Italian spot (name escapes me), or Beaches and Cream.
Also-another vote for Yak & Yeti. It's theming is almost jarringly impressive & I've yet to have a bad meal here. Can't say the same for Pizzafari....
Tusker House is great for breakfast, especially one of those that is pre-opening hours (I would recommend the same with Crystal Palace).
I also like eating at the monorail resorts for breakfast when I'm going to be in MK (Kona, Captain Cooks, Roarking Fork, Whispering Canyon) or eating at Animal Kingdom Lodge for dinner after a day at Animal Kingdom (Sanna, Jiko or Boma), just to mix it up and see the resorts we haven't stayed at.
