Keys on Main.... So fun! They feature 2 piano players/singers who sit at 2 baby grand pianos facing each other. What they play is entirely up to the audience. You bring up a request accompanied by a tip for the pianists ($5 is usually the minimum standard). The songs are played in order of “how much love (aka tip)” is on them. For example, a $20 song will always be played before a $5 song. The “duel” comes from the audience. If someone doesn't like a particular song they're playing, they can stop the song for $1 more than it was originally requested for, and they'll even play a different song to your liking if preferred. The was an awesome experience. We went with Lee and Mitch and got ourselves some delicious Virgin Pina Coladas!! MMM!!! I definitely want to go back!
