Being an AZ native and traveling the world (especially the United States) consistently, when I return home, my first stop is at Charleston's for the grilled chicken and avocado club, a large side of honey mustard dressing, and the garlic mashed potatoes. It is one of my favorite sandwiches on the planet.
I can not say enough good things about this restaurant. They clearly hire well as all of their staff is clean cut, courteous, and congenial.
The atmosphere is nice, the booths are comfortable, it always seems to be crowded but never a wait . . .
I love this place.
