Yami Sushi House

This restaurant appears to be run by a Korean person, and aside from sushi, they're known for their tteokbokki stew. While most Google reviews praise the tteokbokki, the sushi also had quite good quality. They offer a wide variety of fresh ingredients, and although the octopus was a bit thin and had a rubbery texture, everything else was delicious. The tteokbokki stew was also quite tasty. The prices are very reasonable, especially considering this is Prague, making it a restaurant I'd like to visit again.
