The best Mexican food I've ever had in Florence, SC is at the Flea Market at a little place called Jennifer's Taqueria. Don't be deceived by its little shack. Their tacos are phenomenal with all the right fixings! Make sure you bring cash because that is all they take. My favorites are the carne asada and chicken tacos. They all come with a piece of avocado. Make sure you put some of their hot sauce on it. It's so good and authentic!
