Interacting with the map should hide the top and make the only thing scrollable in the viewport the map (with the "Your Alias" bar fixed at the top). Scrolling down causes you to zoom out when your mouse is over the map, which is a really bad experience.
When you scroll down, maybe the "Your Alias" bar has the BitBar logo on the left, and a metro-picker dropdown on the right. This would make the usability a lot cleaner, because it's hard to zoom into a city if you accidentally click on a bar, which slides up the Drink Picker.
There should also be a "Cancel" on the Drink Picker, that doesn't require you to click on the map, because clicking on the map puts the body scrollTop to 0.
