Korean Food is very healthy as it is mostly made of tofu, veggies, sprouts n meat. For an Indian who eats non vegeterian food I guess it would be easier to adapt to korean food, as most of the korean dishes are accompanied with a bowl of rice. Additionally every dish you order is accompanied with many a side dishes – around 7-8 at a time. Most of these side dishes are either sprouts, marinated veggies, tofu dishes, seafood, omlette and kimchi. Kimchi is famous throughout Korea, more like their national dish and you get kimchi served with every dish. Kimchi is basically cabbage or radish pickled (fermented) in Korean Spices. It is supposed to be spicy but not as spicy as Indian food.
For main course they serve various stews (jjigae) – like they have kimchi-jjigae, stew made from kimchi and pork or seafood, sundubu-jjigae, stew made from soft tofu and veggies, mandu-jjigae, stew with dumplings (mandoo), stew with noodles or sprouts etc. Then they have Kimbap (Gimbap) which is a Korean variant of Japanese Sushi Rolls – meat and veggies covered in sticky rice - rolled in dried seaweed. And Bibimbap, which is Korean Rice served or eaten with various mixed vegetables, sprouts and omlette.
Some Korean Restaurants have barbeque on every table, where they serve raw meat (pork) and u can grill them on ur table and eat the pieces wrapped in lettuce leaves and green onion salad. Koreans eat this on special occasions.
Well these are the korean food I have tried so far. There are many others available and some are seasonal. Like ice noodle soup (noodles served with ice) for summer. And many other beef variants for beef lovers like bulgogi and gabli (which I personally dont prefer coz Hindus dont eat beef). Then there are a variety of street food served in Korea too for snacks (which I have yet to taste).
It might seem that Korean food has been influenced a lot by Japan and China (sushi, dumplings, noodles, green tea etc.) but then Koreans get offended when you tell them about this. Well its actually the other way round. It is Japan and China to a very great extent have borrowed the culinary habits from Korean and have taken the credit for it as if it was originated from their own country. Well I am sure this might give rise to a lot of debate. But on my part I prefer to keep mum and savour the taste of the food served on my table.
