The spotlight can feel like a heat lamp from hell or a beacon of light on your unrecognized talent, but whether you can't carry a tune or can sing like a nightingale, your stab at karaoke will entertain crowds. But the best is when you get the chance to sing in front of friends who'll laugh a bit with you and somewhat at you, and not with large audiences who'll definitely be laughing at you. Casablanca is a luminous bar in Bishop Arts that offers private karaoke rooms, the Casanova Karaoke Lounge, with all-day or hourly options. It has a full menu, with plenty of cocktail choices for your friends — who'll surely need them after you bust out an old bore like Lady Gaga's "Shallow." Don't play it again, Sam.
