The Brooklyn, N.Y.-based Great Wall chain has several Maryland locations, including one in Catonsville that opened in 2013. The store feels enormous and comprehensive, with ingredients from multiple Asian cultures. From sausage to jellyfish to an aisle stocked entirely with different types of dried mushrooms, the selection at Great Wall is mind-blowing. It also stocks live frogs: In Chinese cooking, live frogs are sometimes fried, whole and alive, in hot oil, seasoned with garlic, ginger and other spices. In Japan, frogs may be eaten raw, as sashimi. In the United States, both practices have caused controversy; for a brief time in 2010 and 2011, the sale of live frogs was prohibited — in part for ecological reasons — in California.
