Quoting greatgrandmaR
Although I have had a lot of experience eating, I have no experience in the areas you will be traveling in. I will add to karazyal's good advice only the following.
I have found that in most cases, it doesn't pay to try to find a quintessential place to eat. This is particularly true after covid when many restaurants have gone under because people were not going out to eat.
when I wrote this I left out a part of the post. What I wanted to say was that what works for me is when it gets to be mealtime, Look around and pick what looks like a good place to eat.
Occasionally there may be a problem with this if you are on a road trip and find yourself in a rural area with no restaurants of any kind visible, but even then, we usually find something eventually.
