WHY A chance to decide for yourself whether this is the best burger in America.

WHAT When Sang Yoon, formerly chef at Michael’s, said goodbye to haute cuisine to open a pub, he set about creating a world-class hamburger. It’s a rare, dry-aged beef patty topped with Maytag blue cheese, smoked applewood bacon and caramelized onions—and don’t even think about asking for substitutions. The dark, shotgun bar has only a few bistro tables, and even with the larger branch in Culver City, the line’s often out the door. The ever-changing selection of seasonal boutique beers is worth waiting for, but the over-21 rule is strictly enforced, so leave the kids at home.

WHO Beer and burger aficionados.
