1. The Fat Shallot
Though this food truck now boasts two brick-and-mortar locations (inside Revival Food Hall and in Lincoln Park), it's always exciting to see the bright red truck roving the city. Order a grilled cheese with sautéed spinach and caramelized onions or the truffle B.L.T., a massive pile of crispy bacon, arugula, tomatoes and truffle aioli between two slices of Texas toast. It's huge, but you shouldn't miss out on the sides—we're particularly fond of truffle aioli-topped fries.
