Marco's Coal Fired Pizzeria of Denver - Marcoscoalfiredpizza.com - has been reviewed here before, but I'll add that I think it is fantastic Neapolitan pizza. There are two locations in Denver, and not to be confused with Marco's Pizza, which is a chain popping up in Colorado.
I had the good fortune to attend the "Pizza With The Masters" event at Marco's last week. I'm getting ready to put a wood-fired oven on my patio, so I'm trying to learn all I can...this was a great event!
It was wonderful to meet Antimo Caputo, Roberto Caporuscio, Don Antonio Starita, and Fred Mortati of Orlando Foods.
Here is a YouTube video I took of them making pizza...sorry for the somewhat shaky video.
