PEWAUKEE, Wis. (CBS 58) -- Don't want to go out in the rain tonight? Well Bubba's Frozen Custard in Pewaukee wishes you would reconsider. 

The restaurant is raising money to fight cancer in children and it's donating 15% of all sales to the fund started years ago by Bart and Cherry Starr. 

If you stop at Bubba's and order anything- custard, a jumbo burger, onion rings- 15% of your money goes to support pediatric cancer research.

They're open until 9:30 p.m. Thursday night, Aug. 15. 

Sounds like a pretty good reason to grab the umbrella and get some comfort food.
