The bun is a standard brioche, but the toppings have been chosen for maximum impact; that's where the burger sings. Chef Evan Funke's tart, pickley, Thousand Island-esque dressing pulls it all together -- the sharp cheddar blanketing the burger, the caramelized onions, the heap of arugula. At $18, this is on the upper end of the gourmet burger price range, but that includes fries, which are among the best we've ever eaten.
