Bulgogi is a gui (Korean-style grilled or roasted dish) made of thin, marinated slices of meat, most commonly beef, grilled on a barbecue or on a stove-top griddle. It is also often stir-fried in a pan in home cooking. Sirloin and rib eye are frequently used cuts of beef for the dish. Bulgogi is a very popular dish in South Korea, where it can be found anywhere from upscale restaurants to local supermarkets as pan-ready kits.
