You know you’re eating a proper Chicago-style dog when there’s an audible crunch to every bite, between the pickle spear, tomato slices, sport peppers, and snappy steamed Vienna Beef wiener. Cupid’s, a 40s-era walk-up window in Winnetka, understands the assignment. There are four other dogs on the menu, like the enjoyable namesake topped with chili and onions, but if you’re here, you’re heading to Chi-Town, baby. It’s such a briny, pickle-y delight, we’ll even forgive that there’s no poppyseed bun.
