Here in Hawaii we have a  lot of good Yakiniku joints.  Some that are all about value and not so much about quality, and some all about quality and not so much about value.  Fortunately Yagyu does both.  We met up with some HS friends and wanted to eat some Yakiniku on our recent Vegas trip.  I read the reviews and figured we should give it a shot.  We order their combo deal which had a bunch of different cuts of meat, including Beef Tongue, Prime Kalbi, some chicken Karaage, some sushi, some rice, some soup.......yah, a lot.  Great deal with some good quality meat.  We also ordered shrimp.....it was ok, stone pot bi bim bap....good but not great, and the pork toro......nothing special.  The Beef tongue was a little chewier than I'd like,but the prime Kalbi stole the show.  It totally melts in your mouth.  It was so good we had to order another order of it right after.  Soooooo good.  I'll be back and probably just get like 6 orders of the Prime Kalbi itself.
