Luke Tobias, director of operations at Kuma's Corner on the North Side of the city, said the Ghost, a burger named for Swedish metal band Ghost B.C., is a 10-ounce burger with a red wine reduction and an unconsecrated communion wafer, the Chicago Tribune reported Thursday.
The $17 burger is served on a pretzel bun with a portion of slowly braised goat shoulder, aged white cheddar cheese and Ghost chile aioli.
Tobias said there have been some complaints about the menu item.
"People have been kind of upset," he said. "The thing with this is, the communion wafer is unconsecrated, so until that happens, it's really just a cracker."
Jeff Young, producer of the Catholic Foodie blog, said he found the burger offensive.
"It's not the Eucharist, but it's still symbolic," Young said. "For us as Catholics, the Eucharist is more than a symbol, it's a sacrament. At the same time, it doesn't mean that symbols aren't important. ... It is a mockery of something that is holy. The same thing could be said of the band itself."
