What kind of traditional food or beverage do Koreans usually offer their guests at home?

Koreans usually cooked for them in person when their guests visit at home. There are many kinds of dishes to serve. Among them, I think Japchae and Bulgogi are very common and famous dishes for guests in Korea. I think whoever likes and enjoys these dishes if someone tried these for the first time, even foreigners. Because these are used soy sauce and sugar so its taste is very popular and not spicy. We also make and eat it with family for special days like birthday parties and national holidays. I think traditional beverages for guests are sweet rice drink and persimmon punch. We can look at these in the buffets all the time in Korea. These are very sweet beverages but making them in person is a little hard and complex for the younger generation these days. So, I think most people give their guests a glass of coffee at home. But if some guests want to drink them, we can buy them from any market easily.
