I will have two days in Rome with my wife and two kids, ages 8 and 10. They are well behaved, good eaters. I need to make the most of our precious meals (likely two lunches and two dinners). We are not looking for fine dining, but would appreciate suggestions for the best local, authentic Italian fare (we're fine going to a tourist spot, but would rather eat where the locals eat). My kids are big pasta eaters, and we need to show them (and ourselves) the best of this city. We will not have a car, and will likely be staying near the Spanish steps, so location in that area or near public transportation would be ideal.
Thanks for any suggestions.
