This was my first time going to a Korean barbecue, and I must say that I had a good experience. I was expecting service to be mediocre and the place to smell of barbecue, but it wasn't. It was surprisingly better than I had anticipated.
The way it works is that you just look at the menu, choose what you wanted, and check it off on a list. You then give your list to your server and s/he will bring you the raw ingredients. You have to cook it yourself, but that's part of what makes the experience interesting.
My favorites were the sliced ribs and the calamari. The calamari was surprisingly very tender, and the beef was well marinated. Definitely a must try! Cheers!
