I came here with a Bachelorette party, so my review might be skewed a bit. It was so much fun - I hadn't been to a dueling piano bar since college.
They basically played all the songs I requested (win.) and humored the Bachelorette by getting her up on stage to dance (great photo-op.) - everyone was friendly, which helped as well.
$1 beers - nice. And the slightly nasty-tasting buckets of random booze and girly mixers were the best $70 I've ever spent in the name of my friends.
