Prior to finding this gem, we were limited to eating at Ginseng BBQ for late night. Last trip we tried Gangnam. This places blows them out of the water. If you want good meat and good service, come here.
Location/ambiance: this place is pretty far off the strip (3miles?). But well worth the trip. It's set up like Kang Hodong baekjang (for those of you familiar to SoCal). Very clean and well lit. Individual fans and girls per table. Prepare to wait. Lines were still there at 10:30pm on Saturday night. Great for a group of people looking to hangout.
Service: similar to what you would find in LA or OC. Servers all over the place. You can grab any of them and place an order. It was busy so service was a tad slow. They would put your meat order and the meat was individual prepared by a butcher in the kitchen. Spoke mostly Korean but all also understands English.
Food: thy brag that the meat is "angus prime". The meat quality was good indeed. I came late to the party so only got to try the chadol (brisket) and Galbi. Both were wonderful. The side dishes were a plenty. I didn't get to try the mandatory salad so can't comment on that. The "lunchbox" was also good and a must order. I like their complimentary slushy machine in the corner.
I would definitely return. We hung out here til close to midnight.
