When we travel in Mexico we always stop in the small towns and walk around and find a little restaurant to have lunch. It is a good way to sample some of the local fare of the region we were traveling in. Many of the restaurants have open fronts and the cooking takes place on a grill as you enter. It is a good way to see what is being cooked and ask a few questions of the types of food offered. We enjoyed the many meals we had in Mexico except for ones with chicharron.
We noticed that many in the of small towns we would see the owner of the restaurant provide a free meal to an elderly person. It is common practice in some regions to give a helping hand to the elderly and provide them a good meal each day. I made a photo of this little lady in a little mountain town while we were having lunch.
