Hi Shruti,
I have to admit, I got a little giddy with joy reading your question.
Dining at Walt Disney World ranks right up there with some of my favorite attractions. There are so many delicious places to choose from, so the possibilities are endless. My family has our favorites, but we also like to try at least one or two new (to us) restaurants each trip. So, I am so glad you came to the Disney Parks Moms Panel with your question.
At Magic Kingdom, my personal favorite it Be Our Guest Restaurant. The menu has some really unique offerings such as Croque Madame for breakfast or the Tuna Nicoise Salad at lunch. It is considered fast casual dining for breakfast and lunch and table service for dinner. In terms of quick service, my top pick at Magic Kingdom is Columbia Harbour House in Liberty Square. There is lots of seating over two floors and the choices are not your typical "fast food" selection. The New England Clam Chowder and Lobster Roll are my faves.
Over at Disney's Animal Kingdom, I would have to suggest Flame Tree Barbecue for quick service. Being from Texas, I am fairly hard to please on the bbq front, but I have to say, it is quite delicious! Tusker House is a great character meal with a bountiful and yummy buffet. While I have not dined there, I have heard great things about the new table service restaurant, Tiffins, too.
Biergarten Restaurant in the Germany pavilion at Epcot is our family must-do every single trip. It offers a hearty buffet and fantastic Bavarian entertainment. Sunshine Seasons in the Land has flavorful options, many grown right there in the pavilion. Talk about fresh!
I hope this gives you some great places to ponder. For menus for each, you can search using the link above and then each restaurant page offers a "view menu" link.
Bon Appetit
