I love voice box's set up, mostly because that's the kind of karaoke experience that isn't typically excruciating to be around, and mostly because every time I've been there, some sap has picked up the hourly tab for me.
My favorite thing about VoiceBox is that they offer 1/2 pound of peanut M&Ms as an appetizer. About three drinks into the evening, I'll nonchalantly start eating a giant bowl of candy and my friends are always baffled and intrigued.
