✨ AI quick take
全素地瓜球 is a queueing snack stall in a lane off Section Four, Roosevelt Road near Shuiyuan Market and the Section Three Tingzhou Road junction. It sells only original sweet potato balls, hand-portioned, stirred, and repeatedly pressed into unusually large spheres with thin crisp shells and hollow chewy centers. Eat them fresh while exploring Gongguan, especially if vegan snacks and airy texture appeal.
● Small Sweet Potato Balls, Nine Pieces
Nine large balls fill the paper bag, warm and plump with thin crisp exteriors. A bite reveals hollowness, cracking first and then bouncing lightly rather than feeling dense. They retain defined crispness after cooling slightly; the small order is manageable for walking and snacking alone.
● Vegan Sweet Potato Balls
Dough is hand-portioned, constantly stirred in oil, repeatedly pressed with a special tool, and rounded one by one. Fresh balls are golden, crisp outside and soft-chewy within, with delicate sweet potato aroma and no heavy or stale oil. They stay round rather than collapsing immediately as they cool.

Only original flavor and two portion sizes are offered. Solo snackers can begin with the small nine-piece bag; groups can choose the larger serving on site. Eat several hot for crisp-versus-chewy contrast, and save one or two to test them cooler. In a long line, watch each batch being divided.

📌 Editor's summary
全素地瓜球 turns one original snack into a recognizable Gongguan queue. Hand-portioning, stirring, and repeated pressing make every ball large and round without complicated flavors. The small nine-piece bag suits solo walking; fresh balls crack thinly before revealing hollow bounce, while slightly cooled ones retain shape and some crispness. If a golden batch emerges while you walk around Shuiyuan Market or Gongguan Night Market, allow time for fresh frying and eat the first pieces hot.
