We've started gushing about Portillo's almost as soon as it opened, but what's a little more going to hurt? The Chicago-area staple is a master of hot dog arts, but what some people don't know is the glory of Portillo's cheese fries ($2.29 for a small and $2.59 for a large). Since the creamy, hot cheese sauce comes on the side of the crinkle-cut and crispy fries, you don't end up with a soggy mess a minute into eating them. Instead you get a perfect cheesy, potato-y bite every time.
