This is a fun place and a cool place, but I'll have to visit it again to hopefully up the star rating in the future.  I have the misfortune of working out this direction and was pleasantly surprised to see South 21 Drive-in sticking out in a neighborhood of dilapidated buildings and BLAH-chain restaurants/stores.  I originally was worried that the place had closed down since it was never open when I drove by (after 10pm or on Sundays).  Some research online produced the food network visit and a menu and the date was set for my GF and I to drive out here for a visit.\n\nMy dire poverty makes this roughly the one time I ate at a restaurant in many months, so we went into this with pretty high expectations and an equivalent level of excitement.  We got there a little bit later than we had hoped and although the staff didn't rush us, I felt rushed because I knew they'd be closing soon.  We got a super-boy, a cheeseburger, onion rings, and two milk shakes.  I really made a huge splurge and spent about $16.  The burgers were ok, but nothing like I had imagined, they were pretty run of the mill and not nearly as good as I had hoped. I had been craving a non-chain, off the griddle, greasy burger and this one was slightly dry and without a whole lot of taste.  We didn't realize that to get the specialty with \"slaw\" and other \"fixin's\"you need to ask for it \"Carolina Style.\"  The onion rings were OK, but not that fresh, so I'd like to try them again earlier in the evening.   The milkshakes were also just OK.  The people were nice and the owner seemed like a nice guy and he asked us how things went.  (my GF randomly ran into him on his day off and he was also pleasant... I like to buy food/things from good people so this is a plus in my book).  \n\nAll-in-all not bad, but not right on the mark.  I'd love to go back again though and do it right, especially if I could go on a nice summer day (are there any in Charlotte that aren't too hot though!?!).  It's a place with history and fun in a city that has converted most of it's history into parking lots, so it's worth a try!
