I've gone here probably about 10 times or so over the past few years and have ordered the veggie yakisoba, (dolsot) bibimbap, bulgogi, seafood pancake, teriyaki salmon, japchae, and most recently the Kalbi and the ribeye that you cook yourself.
The flavors of all the above are fantastic. The do-it-yourself BBQ was reminiscent of my experiences in S. Korea, which was awesome. It comes with the lettuce for you to wrap the meat in. The side dishes are also very good and refillable!
The staff is usually good. We got this less attentive lady last time that didn't fill our waters... but previously they've been good.
