Karaoke is king at this downtown Tempe pizzeria, and the staff and crowds aren't shy about letting the world know it. The raucous nightly singing sessions — amplified over speakers set up on the patio — rival the din from other Mill Avenue nightspots, attracting a crowd that soon finds the place has entertaining MCs and a jovial, come-as-you-are atmosphere. Anyone's welcome to step onstage, grab the mic, and pick a tune from 414's extensive song list. Some singers have real talent, and others can be as cheesy as the pizza. But few are lacking in energy or enthusiasm, making this our current favorite karaoke night in the Valley.
