I love an Oasis

The Chicago area has these fantastic Oasis(s) along their major highways. I always loved these whenever I made the drive to/from Chicago/Madison.

Essentially, they are like an overpass, spanning over the freeway. You just exit the freeway directly into the parking lot of the Oasis, and once you're ready, you can immediately hop back onto the freeway. The Oasis is indoors, and resembles a very large shopping mall food court. There are 8-12 different fast-food options, plenty of seating, convenience stores, and large restrooms.

Each of the Oasis(s) also have a gas station to the side. They're so handy. I don't know how many other states have them, but I've never seen them anywhere else.
