Release your inner Diva! Come along and sing your heart out, no talent required. In fact the less talent the better ;). True karaoke requires singing off key and out of time - that's the beauty of it!
City Karaoke is one of those places where you hire a private room with a TV and multiple mikes. I haven't been to it but I went to one similar last weekend and it was awesome fun. Because you're not singing to a crowd and there are other people singing with you it's a lot less intimidating. Also, you can change the volume on the mike ;). Cost works out to be around $10-20 per person depending on the number of people.
