sagu food market

I see this little hut everyday on my way to work behind the "Star" gas station on Broadway. What was it? How did it even get a permit to sell food? What kind of food did it sell? It seems to be out of business now, but I always imagined a dim little shop with dried octopus tentacles and old bones hanging from the rafters, with a little old man smoking opium in the back. And, apparently, two liters of Coca-Cola.
Pretty soon the kudzu will take it over and demolish the hut, but right now it's just another enigma in North Knoxville.
