Much hasn’t changed since 1987, but Good Times Burgers & Frozen Custard has stood the test of time. The local burger joint is celebrating its 30th anniversary in “a totally righteous way.” To thank loyal customers, they’re offering a single-scoop cup or cone of frozen custard for only 30¢ (reg. $2.49) on Saturday, September 9 and Sunday, September 10 , while supplies last. Its signature custard is made fresh all day with all-natural milk, cream and eggs. Choose from vanilla or its current featured flavor Oregon blackberry. There are more than 35 locations in Colorado.
