Absolute Comedy is a fantastic comedy club. I've been to this location twice now (once with a group of 20, and once with just 4 four of us), as well as the Ottawa location. All three times I've left quite impressed.
Keep in mind, you should make reservations since the shows often sell out, especially if you're planning to go with a group. Ticket prices vary depending on the day of the week, as do the comedians who come from all over.
I find the place a little different than Yuk Yuk's in that the comedians don't tend to razz the crowd (which I like) and the waitresses carry on serving throughout the entire show rather than just between acts. One thing I have disliked about Yuk Yuk's, that does not happen here, is the comedians criticize the crowd for being a "bad audience". For me that's a big bonus about Absolute.
I have never been disappointed with the quality of the comedians either, though I guess it is plausible that I could have gotten lucky all three times.
I'd highly recommend checking this place out. In my opinion a comedy club like Absolute is the most fun with a big group, but also an awesome way to spend a date night.
