More traditional meals will come with several various dishes. Kimchi is perhaps the most common side dish in Korea and comes in hundreds of different varieties depending on the restaurant and main dish. Traditional kimchi consists of cabbage.
Seafood is predominant in Korea because of its geography. Many dishes include squid, shrimp, tuna and other local varieties of seafood. Kimchi also contains shrimp paste, so those who have shellfish allergies, beware!

Meats such as beef, pork, and chicken have become standard within the last 50 years. Spam is also found in Korean food. These products are now commonplace whereas during the Korean War and post-war, meats were hard to come by. Dishes such as bulgogi, samgyeopsal, and galbi are now readily available to Koreans.

Soups and noodles are also something that are a large part of the Korean diet. Ramen (ramyun) noodles as a snack, also known as cup noodles, can be found in any convenient store or supermarket. The soups in Korea are hearty and chalked full of veggies and tofu as well as the Korean rice cake (daak).
As far as spices go, Koreans tend to use chili paste in a large number of their dishes. Sesame oil, soy saude, salt, garlic, and ginger are also added to give the food a very rich and unique taste.

As you can see, there is a wide variety of Korean foods to try. Be brave and try as much as you can during your stay!
