On Thursday, June 20, Whataburger is helping fans make the most of the Summer Solstice with a free Iced Coffee. The 16-ounce iced coffee will be available from 6 a.m. to 6 p.m. in local time zones and can be customized just like you like it with one of our three new flavors - Vanilla, Caramel or Mocha.
