I have stopped by here many times since it is pretty close to where my parents live. I was never able to check-in though and on a recent visit I realized the reason is that Unilocal has the address totally wrong. This is the convenience store located next to the Post Office in Tubac. It is not in Tumacacori, AZ. Anyway, their food selection is pretty limited. Mostly junk food but they do have some interesting local baked goods and Mexican candy. Also, if you are looking for hard liquor then this place is your best bet without having to drive to Rio Rico or Green Valley because the gourmet grocery store in the Tubac Village only has wine and beer.
