The theme song from the beloved ’80s and early ’90s TV sitcom “Cheers” could easily be used for the L.A. Comedy Club. Not only is it a place where you can take a break from all your worries, but the staff here soon will know your name — if they don’t already.  A large percentage of the L.A. Comedy Club’s patrons are locals who have been following the franchise since it was launched several years ago at Palace Station. After a stint in Trader Vic’s at Planet Hollywood Resort & Casino, it moved to downtown’s Four Queens, then to Bally’s Las Vegas and now is at The STRAT.   Inside the venue you’ll find the hallmarks of a typical comedy club. A mic and wooden stool are front and center on a large stage that is flanked by two video screens. Clips of practical jokes and bloopers are broadcast to patrons before the show begins. There’s a variety of seating options (chairs, tables and booths) — and no matter where you sit, you’ll have a good view.   The format at the L.A. Comedy Club is simple. The bulk of the stage time is given to the The Happy Hour Variety Show starring Julio Gonzalez. Many of the headliners like Felipe Esparza have competed on NBC’s reality laugh fest “Last Comic Standing,” while others including Willie Ferrell, Tom Rhodes, Joey Medina, Butch Bradley and Shang have Showtime, HBO or Comedy Central credits to their name. These headlining comedians are paired with a host from Las Vegas, which is another unique feature of the L.A. Comedy Club. Not only does it offer a top-notch venue for professional comics, but local talent is also nurtured and promoted. Occasionally, a surprise guest or famous friend of a headliner stops by and performs to the delight of customers as well. Be sure to get your dose of laughs during your Vegas vacation.
