We’ve shut down Main Street for this new holiday tradition, which promises a night of galivanting through Downtown Houston’s Historic District. The giant block party will feature a night market, carol-oke, photo ops with hipster Santa, lighting projections and much more. Eventgoers can enjoy food and drink specials and live music at area bars and restaurants. Recommended for ages 21+. Free. 5 PM – midnight. Main between Commerce and Rusk.
