Pi is the scientific play on words for pizza. The logo features the classic Pi symbol – the ratio of a circle's circumference to its diameter, i.e. the perfect circle. To continue this theme, every table has a little glass beaker with fresh cut flowers. It's a simple concept but full of thought and intention which has become Jack and Jamie's trademark at Fortify.

Fortify Pi is located adjacent to Fortify in downtown Clayton. The wall behind the bar is made of old bricks that have been painted white while the opposite side is made up of new and shiny white bricks. A massive light fixture made of beakers hangs over the four foot tall family style table in the back corner while six other tables fill up the dining room. The bar runs almost the length of the building and has stacks of firewood for the pizza oven nestled next to their great selection of craft beer taps and local wines like Tiger Mountain Vineyards from just down the road. The focal point of Fortify Pi is a set of huge collapsible windows that span the front of the restaurant. Half way through our dinner, they opened the windows and a warm summer breeze filled the restaurant.

Open for lunch and dinner Monday through Saturday
