Beat me to it, but here is the fine print (since I cant find a link to this Uber deal):
Request an uberX
QUEENSLOVESuberX covers rides beginning OR ending in Queens (up to $20)
This promotion does not apply to uberTAXI, UberBLACK, or UberSUV
Take up to two rides between 12:00AM Friday (11/29) through 11:59PM on Sunday (12/1)
The awesome food and drink specials from our partners in Queens won't be in short supply, but uberX may be! We're expecting high demand for uberX, so we appreciate your patience.
*Up to $20 off per ride, up to 2 rides. Rides must begin OR end in Queens. The difference of any fare above $20 will be charged to the credit card on your Uber account.
