From frozen pizza to wood-fired pies, some of St. Louis' best pizzerias went head to head at the second-annual Battle of the Slices on Thu., Sept. 12. More than 400 guests packed The Boulevard in Richmond Heights to sample pizza, drink local beer and wine and vote for their favorites in four categories: St. Louis-Style, Frozen Pizza, Restaurant-Style and Wood-Fired Pizza. Congrats to this year's winners: Guido's Pizza (St. Louis-Style), Dan O's Pizza (Frozen Pizza), Felix's Pizza Pub (Restaurant-Style) and Peel Wood-Fired Pizza (Wood-Fired Pizza).
