I consider Trail's End one of the hidden bargains at WDW. It is a great BBQ buffet for a reasonable price. With ribs, chicken, chili and carved meats as their specialties, this isn't the best choice for a vegetarian, although there is pasta, pizza and a salad bar. The only complaint I have is that it is very difficult to get to the restaurant, especially if you are not staying at Fort Wilderness. Since you cannot take your car into the campgrounds, you have to park at the front of the property and take an internal bus to the restaurant. Depending on how many pick-ups the bus makes along the way, this can be a bit of a ride.
Still, I consider it worth the trip.
