Yesterday was the beginning of Pizza Week, and with that came a rundown of the 9 can't miss places to eat pizza in Nashville. But what would the week be without an epic pizza throw down? That's right folks, voting starts right now to crown the top pie in town. Now for the details. Eighteen of the city's most popular pizza purveyors have been grouped randomly into three sets of six. Vote for your favorite in each set, and the top three from each will move on to Round Two tomorrow. Voting is open until 9 a.m. tomorrow morning.
