I happen to work in the casino that the LA Comedy Club is in. Considering the location, it's surprising there is any entertainment in the building at all, but it does tend to work well here.
Each week there is a rotating set of performers. What may not work for you one week may be much more entertaining the next. For the price, however, you will get enough laughs for your money. At the most the tickets are $34.95 and include either two drinks or a buffet; if you're not a member of the Station Casino's loyalty card program, they give you a free ticket if you buy 1 drink ($9.95 total cost).
Add to all of this the overall low cost of dining at Palace Station and you can have a decent night here. Both Cabo and Pasta Palace are part of Restaurant.com's gift certificate program where you can purchase a $25 (toward's a $35 total purchase meal) gift certificate for $10 or less.
Since I am reviewing the club itself, let me say that it is big enough to fit 100-200 people comfortably with tables and booths, yet it will never be too full that you feel boxed in. The acoustics are alright and the microphones can be a little loud, but this is Palace Station (lots of motorized chairs, oxygen tanks and hearing aids).
Check out the performers online before you go and if they seem entertaining, you'll have a good time!
