I'm not sure it's my signature dish, but my most requested and most frequently made big company meal is a Korean BBQ spread. I'm not Korean, but we all love it. I was a Korean language voice interceptor in the army in my youth, and developed a huge appreciation for Korean food, including bbq, during language school and being stationed in Korea.
Generally I make 2 meat dishes (out of beef bulgogi, LA Kalbi, spicy bbq pork, and spicy bbq chicken) with japchae and rice to go with it. Then 4-10 side dishes (choices are things like kimchi, radish kimchi, cucumber side dish, potato side dish, dried squid side dish, candied anchovies, soy or mung bean side dish, spinach side dish, Japanese potato salad, braised lotus root, etc etc--I try to mix it up.) Occasionally I'll throw some fried dumplings in as well, but not usually.
