Good South Korean Restaurant

South Koreans and foodies of Budapest, please help =]
We've recently watched Castaway on the Moon (Kimssi pyoryugi) with my girlfriend, who loves this movie. I want to surprise her with some noodles with black beans, like in the movie.

Which restaurant or takeout would you recommend in BP?
So far, I've found Seoul House Restaurant in the first district. I'm not necessary looking for the most expensive place, but I also don't want to take her to a dodgy place.

Thanks in advance! ^__^
