Do not write this airport off just yet. There are still great restaurants and shops inside. Stop into the Great Lakes Brewing Company and have a pre-flight drink. You will not regret it. It may not be as busy as other major airports but it has a nice calm atmosphere with friendly staff and some exciting features.
On your way out make sure to check out the Superman tribute next to baggage claim. After all, Cleveland is his birthplace (OK, Krypton but still he was created here).
Oh and free WiFi!
