BLK Burgrz is a burger restaurant in Ladera Ranch. If the restaurant had any peers, they would be Slater’s 50/50 and the Counter. As at Slater’s, it cooks a bacon-and-ground-beef-hybrid patty. As at the Counter, it gives you a checklist of possible toppings. But it blows past both as one of the most expensive burger restaurants in the county. Since every burger is Kobe -- or rather, American Wagyu sourced from Snake River Farms, an outfit you may have never heard of until it’s mentioned in restaurants such as this -- the cheapest burger will cost $17. The waiters will inform you of the beef’s pedigree as soon as you sit down. Are they telling you to justify the price? To remind you you’re not in a normal burger joint? Maybe. But you realize that yourself when you look at the menu. On it are deep-fried burgers and ones for which lamb or sausage is blended with the Kobe-grade ground beef. And then there’s the $55 Kobe steak dinner that comes with a certificate of authenticity.
