Absolutely the worst. My husband and I were in Charlotte for the day and were looking forward to trying this drive-in that not only was featured on Triple D but which had so many positive Yelp reviews. Unfortunately, our experience was in line with the minority of reviewers who gave this place low ratings.
My husband ordered the fried trout plate and I got a burger "Carolina style" (mustard/onions/chili/slaw) and some of their supposedly fabulous onion rings.
The food was, for lack of a better description, rank. The chili on my burger had a very unpleasant aftertaste and the slaw had no taste at all. I tried scraping everything off the burger and covering it with catsup, but it was still inedible. The "fabulous" onion rings were brittle, with none of the "yumminess" of delicious onion rings. My husband ate a few bites of his fish, also proclaimed the slaw completely tasteless, and was done. He also said the tartar sauce which so many people raved about tasted "off" and not at all like real tartar sauce.
So that was it. $20 plus $2 tip for curbside service -- a total of $22 for nasty tasting, verging on rancid, food. Five hours later and we're both still feeling a bit queasy and not the least interested in eating anything else today.
I have no idea how this place has thrived for over 50 years. You can get vastly better chili burgers and onion rings at Sonic!
