Great selection of songs; it's really cool that you can line up your favorite songs from a Smart Phone. My phone is a shotty BlackBerry that I've had since uni so I could only watch others in envy as they whipped out their iPhones and chose songs.
The bar selection was reasonably priced for Toronto standards; Corona and Bud Lite Lime were both around $7. The room must have been reasonable as well as I paid $10 for the four hours that we were here.
Location is convenient. B+K is on the second floor; get off at College Station and it's on the west side of Yonge, south of Gerrard.
Bar + Karaoke Lounge = 5 Stars
