Heavy metal stars GWAR have launched an online campaign to raise funds for a "gourmet" junk food restaurant.

The rockers are calling on fans to donate to a fundraiser on Indiegogo.com, with the proceeds going towards the start-up cost of the Gwarbar in Richmond, Virginia.

With a goal of $50,000 (£29,922) and location already picked out, they are aiming to use the money to renovate the kitchen to serve "gourmet junk food", as well as build a beer garden and a smokehouse for their own "Gwar-B-Q".

In the description for the campaign, the bandmates note the death of frontman Dave Brockie in March (14) inspired the remaining Gwar members to follow through on their entrepreneurial plans, saying they are "more determined than ever to make one of his last dreams a reality".

Fans who give to the campaign can receive rewards such as a free entree at the restaurant, a cooking class with bandmember BalSac, or have a signature drink named after them if they donate $2,500 (£1,496).

The campaign, which kicked off last week (22May14) and runs until 21 June (14), had raised more than $6,000 (£3,591) by Wednesday (28May14).
