After being forced to shut down his original pop-up in March, the owner of Old Greg's Pizza began making his sourdough pies at home to share with friends, family, and chefs he knew. The style was something new in Miami: square pies made with a sourdough base, covered in crispy pepperoni cups. Once word spread, thousands of people began requesting a taste of Old Greg's pies. So in July, owner Greg Tetzner partnered with Miami chef Brad Kilgore and opened a pop-up for takeout. On Wednesdays, the pop-up hosts 'pizza drops' through their website where customers can sign up to get a pie. With so much demand, many are forced to wait weeks for a taste.
