I would call this a hidden gem of Vegas! I found Gangnam on Yelp and Yelp reviewers did not steer me wrong! It's off of Paradise and Harmon, just across the way from the Hard Rock Hotel and Casino (in the same area as the CVS). We had to call because we didn't see a sign in the advertisement section, but it's there!
When we arrived it was happy hour. Their happy hour beer was INSANE! We paid $8.50 for a pitcher of beer! $8.50!!! Our server was so awesome! Since this was our first time here she helped us figure out what we wanted on the menu AND also helped with putting the meat on the grill and letting us know when it was ready. This was probably one of the most reasonably priced and filling meals we had in Vegas! They're meal for two combos are huge! Don't be afraid to ask for their help (cooking or picking something to eat), everyone is really nice! The ambiance is really good too! When we were on our way out there was a bit of a line, so I definitely recommend calling ahead and making some sort of reservation.
If you're trying to walk to this place from the strip and it's well over 100 degrees, reconsider! There isn't much shade, the sidewalk is narrow and it isn't worth it! I learned the hard way lol!
We will definitely be back!
