There are a few menu items that are not allowed on the package. Most restuarants that offer lobster exclude it (and any combination entrees that have it - like steak and lobster). Some restuarants do not allow appetizers that are meant to serve more than one person or specialty drinks.
Other than that, you get to choose anything on the menu. As already mentioned you get an appetizer (or soup or salad), an entree, dessert and drink (coffee, soda, milk, lemonade, water, etc.).
