Diamond Nail at 2262 Highway 42 North, McDonough, Georgia.

They are always friendly here. Most techs do a great job. I have only experienced once or twice where I wasn't completely satisfied. I've been going here for 3 years now so it took some time to find a regular tech that I can ask for. Now I try to get the same person each time. They have a huge SNS stock and are very affordable compared to other places in the area. Its a popular spot so I don't recommend going on the weekends. Its usually packed!
