Walgreens Southern Highlands is much like every neighborhood Walgreens in Las Vegas. The only thing that sets them apart is the level of services.
Southern Highlands gets 4 stars because the staff is always friendly and the pharmacy is quite helpful. The only thing is they often seem under staffed and lines back up. It seems 50/50 to me if I'm going to have to wait or not. And it is not that I'm just coming at peak hours.
All in all if you are in Southern Highlands it's definitely worth going in as the next Walgreen is miles away.
