There's no shortage of standup burgers in Dallas, but recently Michelin-starred chef Bruno Davaillon helped to reinvent Up On Knox into a French bistro, appropriately called Knox Bistro. The previous concept had a good burger, but this new iteration is all oo-la-la. A thick patty that's cooked to order comes smothered in a creamy peppercorn sauce and topped with caramelized onions. Don't try to dig in with your hands, this is a cutlery burger. Order fries with an extra side of that peppercorn sauce. Then sit in a corner and dig in.
