Who wouldn't love a giant organ, especially when it comes with a pizza? Organ Stop Pizza in Mesa prides itself as home to a massive 5,000-pipe Wurlitzer, the largest Wurlitzer theater organ in the world. Built in 1927 and revamped and put to use again in 1975, the thing, powered by four huge turbine blowers, totally wails; musicians play everything from the Star Wars theme to "Phantom of the Opera." Also, these guys deserve major credit for sticking to song themes. At the end of a patriotic medley, a giant American flag is unfurled behind the organ. Four console-controlled cat marionettes dance along to "Alley Cat." And when the song "Part of Your World" from Disney's The Little Mermaid is played, bubbles descend on the room.
