MILWAUKEE — For more than four decades, Saz's has been part of the Summerfest experience, serving festivalgoers, private event guests, and even the artists backstage at Henry Maier Festival Park. Since 1979, the Milwaukee favorite has grown from a single food stand into one of the festival's most recognizable and reliable food partners. Saz's first joined Summerfest as the original food vendor for Miller's first stage, then known as the Miller Jazz Oasis and now the Miller Lite Oasis.
