It may not technically be within Chicago city limits, but the subs at Alpine in nearby Elmwood Park are worth a visit. This takeout-only sandwich shop has a short menu of classics, plus housemade sides like potato salad. Get the namesake “alpine,” a classic italian sandwich that’s been on the menu since 1955. It comes on soft, chewy bread and has a complex flavor profile—with a hint of garlic—that gets even better when you add their housemade hot giardiniera. A nine-inch version will run you less than $10, but spring for the 18-inch if you want this masterpiece for breakfast, lunch, and dinner.
