I finally tried the legendary Woonam Jung kalbi thanks to a not-so-little UYE hosted by Jen S. Oh yes. WJ's kalbi is the best in town. Supposedly, they get their kalbi from LA. For $24.99 AYCE, WJ is definitely worth the visit.
Other things we tried that were delicious: chadolbaegi (brisket), hyeomit gui (beef tongue), maeun daeji bulgogi (spicy pork).
Not everything was amazing. The gaeran jim (steamed egg) was burnt and you could taste it throughout. The other meats we ordered were decent, but other KBBQ joints do it just as well. And the service, though quite good at first, seemed to grow weary of our non-stop ordering. But I won't fault them for that. We were a demanding bunch.
The kalbi alone earns them five stars.
