If you enjoy classic hot dogs and vanilla ice cream, and are looking for something to do on Labor Day, look no further. In collaboration with San Gabriel Valley's Fosselman's Ice Cream Company, Dog Haus will be giving away free soft serve on September 7 at all 10 SoCal locations. For a full list, click here. If you miss the free ice cream, don't worry. From now on you can get more than hot dogs on King's Hawaiian roll buns and chili cheese tots. The always-satisfying vanilla soft serve will be permanently available in a cone or a cup, along with salty caramel and Dutch chocolate milkshakes.
