Final answer:
Restaurant policies or business product offerings determine which entrees can be substituted with no additional charge. It varies by establishment, and checking the menu or asking serving staff is recommended to get accurate information.
Step-by-step explanation:
The question about which entrees can be substituted with no added charge pertains to a restaurant's menu options or a business's product offerings. Generally, whether you can get substitutions on entrees without any extra charges will depend on the specific policies of the establishment.
Many restaurants have a set of options that can be swapped out, such as different types of sides or bread. For example, you might be able to substitute fries for a salad or get wheat bread instead of white with no additional cost. However, some substitutions that require more expensive ingredients or additional preparation may incur an extra charge.
To find out which entrees you can get substitutes with no extra charge, it's best to check the menu for any notes on substitutions or to ask the serving staff directly. They can provide you with information on any possible extra charges based on the restaurant's policies.
