There's an old best burger thread for Columbia but it is time for an update. If you have some recent discoveries please post them.
I recently visited Pawley's Front Porch on Hardin Street in Five Points. It is certainly a contender for best burger in the area. Apparently they grind the meat there, and so you can order your burger as rare as you'd like. They feature about 10 different burgers with creative combinations of toppings (the Beaufort Burger has fried onion rings, a fried egg, smoked ham, and cheddar; the Wadmalaw Burger has chipotle sauce, bacon, fried pickles, and cheddar; the Edisto burger has goat cheese and caramelized onions, etc. -- see menu pics here: http://www.urbanspoon.com/u/menu/1467...) . The burgers are meaty with a slight external char and come with a steak knife stabbed into the top of it, holding the burger and toppings together in a way a mere toothpick would fail to. It's also convenient for slicing your burger in half to make it more manageable to eat and check to see if its cooked properly. Really quite good, with good, homemade fries, too.
I also had a great burger at Cock n' Bull once, but I haven't been back and apparently they are closed and moving to a new location. I hope their burger returns.
