Haunted House Party

Preview: written before the show opened

As a teenager in the early 1980s, Gene Hunt was playing the Warehouse and the Music Box, the clubs where Chicago house began. On Halloween he takes Shedd's Bubble Net Stage, while DJ Heather, a Smart Bar and Spybar regular, plays the Grand Hall.

It's a 21+ costume party with the whole aquarium open, touch experiences included. You can catch a Shark Chat in Wild Reef at 7:30 or 8:30, then the Kelp Forest Chat in Oceans at 9. Some habitats are dimmed for the animals' night, and Wild Reef closes at 9, so the sharks call it a night nearly two hours before the DJs do. The menu runs to Birria Grilled Cheese and a mezcal-and-Strega cocktail called Witching Hour.

Tickets are $29.95, or $19.95 for members, and photo ID is checked at the door. Costumes are encouraged, but no full-face masks or prop weapons. Last entry is 10 p.m., last call 10:30, and it's all indoors this year while the North Terrace is closed for construction.
