"The burger at Gus’s is best when shared. The rich patty is made from a blend of pork, chuck, and dry-aged beef, then topped with caramelized onions, aged cheddar, cornichons, and dijonaise. At $22, the burger is a pretty standard deal these days as far as burger prices go. Did you know: This burger, once off-menu, was so popular it landed on the menu permanently." - Robert Sietsema
