Years ago before moving to Charlotte, I lived in Dallas, TX and would fly out here several times a month for business. I worked in the Ballantyne area off Johnson Rd. (512). The original 521 BBQ was my first exposure to Carolina Style BBQ and set the bar very, very high. To my excitement, we found after moving out here that there is now a satellite location in Fort Mill much closer to our house!
This is your traditional BBQ joint. The Fort Mill location is a little more upscale than the original by offering a great selection of beers with a couple rotating local craft offerings.
While I have tried a large cross section of their menu, my "GO TO" meal is their 2 Item Combo Plate with Ribs and Sausage. Lord help me, their sausage is AMAZING! While some like fried, I encourage folks to also give their onion rings a go as well!
Also, while it's not provided on the tray of sauces they bring to the table when you order, be sure to ask for their Mustard BBQ sauce. You'll be happy you did!
In summary: BEST BBQ EVAR!!!!
