Halloween Party at Fair Oaks Roost is a spooky-season night out in Fair Oaks Ranch, just outside San Antonio. A DJ spins tunes through the night, so you can dance in your costume and enjoy the party vibe. Stick around for the costume contest, where gift certificates go to the top individual finishers and a first-place couple. Fair Oaks Roost is a relaxed local spot, a great setting for a Halloween bash with friends.
