VIA 313 GAPCO Pizza Today's 2018 Young Entrepreneur of the Year Sammy Mandell keeps taking his pizzeria to new heights. Greenville Avenue Pizza Company entered the list at 95 just a few short years ago and has shot like a rocket up to No. 61 with over $4 million in annual sales with its two Dallas units. Via 313 has been a leader in the westward movement of Detroitstyle pizza. The Hunt Brothers started slinging square pies from a food truck in 2011. With a mix of full-service restaurants and permanent pizza trailers, Via 313 does a smashing $12 million in annual sales. Everything in Via 313 pays subtle homage to the brothers' beloved Motor City. In addition to its Detroit-style pizza, the pizzeria's menu also features popular bar pies. Via 313 is a fixture on the national radar - from the likes of Eater, Food Network, Zagat, The Daily Meal and Thrillist.
