Get ready for a Halloween party filled with music, costumes, drinks, and a few chances to walk away with a prize.
DJ Mondoscious will be keeping the music going throughout the night, setting the mood for a Halloween celebration you won't want to miss.
Come dressed to impress and enter our Best Costume Contest! Whether you're going scary, funny, creative, or completely over the top, we want to see what you've got. One winner will be selected, with the prize announced during the event.
We're also holding a Halloween Raffle with up to four lucky winners throughout the night, so keep an ear out for the announcements!
And of course, we'll have drink specials and Jell-O shots to keep the Halloween festivities going.
