I'm looking for really good, authentic Korean in the general area of Philadelphia--where should I go? I've heard conflicting reports as to whether good Korean actually exists in Philly, so I figured I'd ask the Philly hounds here. I'm coming from Northern Virginia (home of some really, really incredible, real deal Korean chow), and I don't want to be disappointed. What restaurants have Koreans filling seats?
ALSO, anywhere I can get Sannakji (fresh octopus tentacles)? I know it's a bit of a novelty here in the states (because they're still moving and squiggling around on the plate), but is there anywhere that serves it here, or anywhere old school enough that they might be happy to prepare it for me? My brother's never had it, and I think he'd enjoy and appreciate the experience.
