I'm gonna be spending about 5 months in Oviedo, Spain and I wanted some recommendations of places where I could go to get the best of Spanish cuisine. I'm interested in finding good places were locals themselves would go, not expensive touristy places. Recommendations?

Lately I've had a burning desire to eat some authentic Korean food but not quite sure as to where I could go in the city. I'm open to all suggestions, and price range/directions via SEPTA are a plus! Cheers!
