We all know people who are sorry that they accepted a job offer or who earn a degree or certification they found to be useless or inappropriate for them.
Done well, informational interviews -- collecting good information from a variety of sources before you make an important change of career direction or move to a new job -- help avoid many mistakes, and are a very good idea.
Without collecting information, successfully changing careers or finding a great new job can often be more a matter of luck than a well-reasoned move to a better future:
So, taking the time and making the effort to do some "due dilligence" before taking the next step in your career, whether that's a new job, a new career, or a new employer, is smart self-defense.
Informational interviews help you make a more-informed decision before you take that leap into a new field or in a job with a new employer. You will learn the right questions to ask to get the information you need.
Collecting relevant information is key to your career success. Once you have made the move to the new field/employer, you will probably be stuck for as long as a year before you can gracefully move on. If that new field or employer is a bad fit for you, your perfomance may not be great which will be refelected in your performance reviews and references.
Taking the time to be well informed will pay dividends in the future as you, potentially, avoid bad career decisions and/or bad employers.

By asking people for advice, which is really what an informational interview does, you are paying that personal a compliment, and they know it. So, this may strengthen your relationship with that person.
Since you end most interviews by asking for the name and contact information of someone else to talk with, you are also expanding your network, hopefully in a direction that will benefit your career.

A better (and larger) network will typically give you an inside track to opportunities inside that network. So, if one of your network connections learns of an opportunity inside their organization that might be a good one for you, you may be contacted by them. Consequently, you could become an "employee referral" candidate, giving you the best probability of being hired and, usually, rewarding the employee who refers you a bonus from the employer.
Whether you are starting your first real job search or your first job search in many years, the more interviewing you do, the better you will become at doing it. The experience of interviewing, particularly going to a new location and meeting new people, will become less scary as you do more of it, and survive the process.
Start these interviews with people you know, or have at least met once or twice. Then, move on to people you don't know. This will enable you to handle the intimidate "public" aspects of the whole job interviewing process. You'll also learn how people recover from mistakes in the interview, as well as the most effective way to communicate, to present yourself and your experience in the best light.
As the person conducting the interview, rather than the person being interviewed, you will gain insight into what is happening on the interviewer's side of the process -- juggling schedules, watching clocks, asking the right questions to dig out the information you need, etc. You'll learn their concerns. You will also learn how important it is to be well-prepared for the interview so that you will ask the right questions to receive the answers you need. You will also probably learn more about reading body language.
