Restaurants may have policies regarding refunds or returns in specific situations, such as incorrect orders, food quality issues, or unsatisfactory dining experiences. If there is a problem with your order or meal, it's best to bring it to the attention of the restaurant staff or management immediately. Some restaurants might require reservations for certain events or busy times. They may also have a cancellation policy, where guests may need to cancel or modify their reservations within a specific time frame to avoid penalties.
