I used to live in Charlotte several years ago and whenever I return, I never miss a chance to go to my absolute favorite authentic comfort soul food restaurant. I always order one of my favorite all-time meals: fried chicken thigh, mac & cheese and yams (beware - they're candied!) with a sweet tea. You also get a mini-loaf of corn bread with honey butter. Best meal ever!
The waitstaff is always super casual and exude the "southern charm" you expect from a southern diner.
Most people who live in Charlotte already know about Mert's (it has been there forever)... But if you're visiting Charlotte, do yourself a favor and stop in for a meal - you won't regret it!
