Hi Diana!
Congratulations on your upcoming 10th Anniversary!
My top recommendations
for family dining in a 'nice' atmosphere for your celebratory dinner would be
'Ohana at Disney's Polynesian Resort and
California Grill at Disney's Contemporary Resort.
The atmosphere at 'Ohana ("family" in Hawaiian) includes deliciously prepared fire-grilled meats, salad, sumptuous pineapple-coconut bread and the most delectable dessert in all of Walt Disney World! You can even enjoy a view of the Wishes fireworks over Cinderella Castle in the distance. The lights inside 'Ohana are dimmed and the soundtrack is even piped in for your enjoyment. It's the perfect family atmosphere. 'Ohana requires 1 table service credit per person under the Disney Dining Plan.
If you'd prefer something slightly more upscale while still retaining a family environment with great dining options and special extras, give California Grill a try. This 'signature' dining experience is located on the 15th Floor of Disney's Contemporary Resort. Enjoy sweeping views of Magic Kingdom Park lit under the night sky and the tranquil Seven Seas Lagoon. Venture out onto the outdoor viewing deck for an unforgettable view of Wishes as it bursts into the sky over Cinderella Castle. It's an experience like no other, truly special and unforgettable. California Grill requires 2 table service credits per person under the Disney Dining Plan.
Visit the links to both restaurants I've provided above for further details on menu items offered at these locations. I think you'll find their locations to be convenient for your return to the Wilderness Lodge following your special meal.
Wishing you a simply Magical time as you celebrate your 10th Anniversary at the Happiest Place On Earth Diana!
