A year-round Halloween-themed bar and restaurant opened this fall on Riverside Street in the former home of Volcano Restaurant Bar & Grill.

Zero Bar & Grille is located at 155 Riverside St. The massive 9,000-square-foot venue includes an 2,500-square-foot entertainment space called Club Zero in the rear of the building, where a DJ performs Fridays and Saturdays. The bar and restaurant seats up to 200 customers, and the back room can accommodate up to 175.

“I love Halloween,” said owner Liv True, who decorated the front of the building with big skeletons and gargoyles, while bats, skeletons and other spooky decor fill the interior. The menu offers salads, sandwiches, burgers, fries, fried chicken tenders, drinks and desserts with Halloween-themed names: Afterlife Melt; Graveyard Griller; Crypt Crisps; a Bloody Screwdriver; and a Graveyard Mud Pie.

This is the first time owning a bar or restaurant for True, who also works at her family business, Overhead Door Co. She worked for four years on the staff at Seasons Grille & Bar, which occupied the space before Volcano.

“When I worked there, people would order chicken tenders and burgers for their dogs, and it drove me crazy,” said True, who named her dog Zero, after the ghost dog in the “The Nightmare Before Christmas” movie. “So I created a doggie meal, which is what I feed my dog, with rice, grilled chicken, broccoli, cauliflower and carrots.” A portion of proceeds from the doggie meals and treats on the menu goes to a rotating animal shelter.

True has tried to make Zero Bar & Grille as dog-friendly as possible, without actually letting the pooches inside: She includes water bowls and special dog cots for any dogs accompanying people at Zero’s outdoor seating.

Zero Bar & Grille is open Monday through Thursday from 4-10 p.m., and Friday and Saturday from 4 p.m. to 1 a.m., with events offered all week long, including karaoke, music bingo, cribbage, self-defense classes, live bands and DJs. True added 5 pool tables so a pool league could play in the space.

“I’m utilizing every square inch of this space so that I can recoup some of the money I put into it,” True said.
