3. Covo Greek Street Food
After closing its Chicago location after just one year, Covo has set up shop in the city’s suburbs—this time with a slight name change that emphasizes the on-the-go nature of its fare. Otherwise, not much has changed from its earlier iteration. Customers choose a pita, bowl, salad or plate, and move down the line to select a protein, toppings, sauces and more. The fast casual also offers loukoumades, a type of Greek donut that can be fried and served in around one minute.
