"This gourmet sandwich spot channels childhood grilled cheese memories into a creation fit for grown-up tastes with a version that combines melty Muenster, sauteed spinach, and caramelized onions between two slices of sourdough. It’s also available at the Fat Shallot food truck and outposts in Evanston, the Merchandise Mart, and Sterling Food Hall (formerly Revival)." - Ashok Selvam
