THE DRACO TAVERN

From back cover Tor paperback December 2006:

When a tremendous spacecraft took orbit around the Earth's moon and began sending smaller landers down toward the North Pole, the newly arrived visitors quickly set up a permanent spaceport in Siberia. Their presence attracted many, and a few people grew conspicuously rich from secrets they learned from talking to the aliens. One of these men, Rick Schumann, established a tavern catering to all of the various species of visiting aliens, a place he named the Draco Tavern.
