Taco, booze, and booming music. It’s time for Taco Boy’s third annual Halloween party, with DJ NattyHeavy, a Halloween specialty margarita, and a costume contest. Compete for the $1,000 grand prize as an individual or go for the $500 gift certificate to Taco Boy as part of a group. “It’s for sure the best thing going on downtown on Halloween, and it’s only $5,” says Taco Boy’s Heather Pruitt, who predicts the costume contest will be fierce — so get busy on that costume. Needless to say it’s 21 and up, and underagers, no, your costume can’t be of a 21-year-old.
