Fans of towering burgers sandwiched between slightly sweetened sourdough buns will soon have one more spot to snag the delectable eats: Biff Buzby’s Burgers is opening a second location. The burger joint took to Facebook Sept. 18 to share that it would be expanding into a spot at 2769 Nacogdoches Road, which will offer ample patio seating and a kids playground — amenities not available at the flagship Toepperwein location. The new spot will open at the former home of Windmill Ice House, near MacArthur Park.
