I grew up on Piggy Park hamburgers and BBQ. They have great Brunswick stew (there's not many other stews I eat), and great slaw dogs also. This isn't about "atmosphere" or "ambiance", it's about food.
The scramble burgers are enhanced by a special sauce: a mixture of mustard, ketchup and other ingredients. The BBQ is sliced and plentiful, cooked the old-fashioned way: slow-smoked over an oak fire. Ride around the Northside area any Tuesday afternoon if you don't believe it. The fries are the best in the area, real potatoes cut and fried. Not mushed and formed like today's fast-food McRestaurants.
Here is a bit of trivia: Wayne Cochran wrote the song "Last Kiss" while sitting in the parking lot of the Piggy Park when it was located on Highway 19 S.
