Umami Burger has gone the way of the chain, but the company's foodplex on historic Broadway is one of a kind. Mezze's Micah Wexler is behind the Cure's deli classics like smoked fish and pastrami. PIGG offers the creations of Bay Area nose-to-tail enthusiast Chris Cosentino—think cured pork parts and pork-fat fries with a pig-brain sauce. Jordan Kahn's & a Donut delivers exactly that, including a limited-time-only foie gras pastry, and a cocktail bar pours alcoholic slushies. Of course you'll also find the signature burgers. We had more fun than culinary revelations here, but that's fine.
