Hi Jessica and welcome to the Disney Parks Moms Panel.
Tusker House Restaurant is one of my family's favourite places to eat at the Walt Disney World Resort.
At this moment in time, lunch is served from 11:00 AM - 3:30 PM and dinner is served from 4:00 PM - 6:30PM. (You can check the times for the day of your intended visit by looking at the bottom right hand corner of the Tusker House Restaurant page of the Walt Disney World website, clicking on the calendar icon and selecting the date of your visit.)
According to the menu section on the unofficial website www.allears.net, the price of this all-you-care-to-enjoy-buffet varies based on the time of year (peak seasons vs regular season), and even on the day of the week (weekday vs weekend).
LUNCH: The general price ranges for lunch:-
Adult price range: $31.99-$37.99; Child (ages 3-9) price range: $17.03-$22.99
DINNER: The general price ranges for dinner:-
Adult price range: $31.99-$41.99; Child (ages 3-9) price range: $17.99-$24.99
Tax is included; gratuity is not included. A standard, non-alcoholic beverage is included in this price.
I do hope that this gives you a guide as to what the cost of lunch and dinner is likely to be.
Wishing you a magical trip filled with memories which will last a lifetime!
Emma
