If you've got time to kill during a long layover at the Frankfurt airport this is an interesting pit stop. While you can easily walk to here from a walkway connected to the airport you're going to have to leave the secure area and go through security to come back. The Squaire is an interesting amalgam of a train station, glass dome, office building, hotels, retail shops, and restaurants. The food selection is quite varied ranging from a Burger King to some nice looking restaurants. I didn't have a lot of time to explore because I spent most of the layover sleeping at the attached Hilton Garden Inn (which lets you reserve a room for just the day). Still it was nice being able to grab a quick bite before heading back for the next flight. read more
