So I always go to play DDR at round 1 (at the amazing X3 cabinet they have) and see the karaoke booths on the way in and think they'd be fun to do with friends, so I made a meetup to do both. Hurray :D
Prices for everything are here http://www.round1usa.com/price.html but to rent out the karaoke booth it's gonna be $3 per hour for karaoke per guest or so plus 1$ for something off there menu, and whatever you want for the arcade.
I figure we'll just hang around the arcade till everyone shows up, then go to karaoke. My cell phone number is 1-714-624-5497, just send me a text whenever you get there and we can meetup.
