We love going to LTT and try to have dinner there on every trip. When I say "we", I am talking about all adults --DH, DDIL, DS and me. The food is good and plentiful but that's not why we go there. We find that LTT had the VERY BEST character meal in WDW. The characters there seem to be more fun than at other character meals and seem to get to every table several times during the meal.
As for the food, it's not gourmet but it's good and plentiful. You start with a salad that usually has a raspberry vinaigrette dressing and a large basket of rolls and butter. Then you get a plate with Yankee Pot Roast, turkey, ham and stuffing (everything is served family style). The sides are usually mashed potatoes, macaroni and cheese and a vegetable (on most of our trips it has been green beans sauteed with garlic -- YUMMY!). Dessert is apple or cherry cobbler and ice cream. Some Disboarders have complained about the food -- particularly the mac 'n cheese because it is Stouffers "right out of the package." Well, the restaurant is sponsored by Stouffers. In any case, this is an all you can eat meal. I can say that we've rarely had seconds -- we are usually too stuffed.
I hope that you enjoy LTT as much as we do.
