Ticket prices vary for each comedian performing. Please see our calendar for comedian performance dates, show times, and prices.

You can purchase tickets online via our website, in-person at our Box Office, or over the phone. The service fees (if applicable) are the same regardless of method of purchase.

Phone Number: 909-484-5411

You must be at least 18 years of age (unless otherwise specified) to enter and at least 21 years of age to purchase and/or consume alcohol. You will need to show photo identification to enter our club. Valid forms of ID are as follows:

  • State issued Driver’s License
  • State issued ID
  • Official Passport
  • Military ID

We highly recommend purchasing tickets in advance because we cannot guarantee tickets will still be available for purchase at the door. We do not hold seats or tickets. Once the tickets are sold out the only option for a sold out show is a waitlist which is done at our Box Office on a first come, first serve basis and there are still no guarantees of seating. We are an Open Seating Showroom (1st come 1st serve General Admission seating). You have the option to reserve seating and get front-of-the-line access by using our Group and/or VIP Services.


Show times vary. Please see our online calendar for dates and show times. Doors for most weekday shows open 30 minutes before. Friday through Sunday doors open 90 minutes before show time for dinner guests.

We consider ourselves to be a more upscale venue than your average comedy club since we are a full service restaurant and theater. Anything from casual (sneakers and jeans) to black tie is acceptable, however hats and other items that may be a distraction to others seated in the showroom are not recommended. Please no tank tops, sleeveless shirts for men, or biker style gear for anyone.

Unfortunately we do not mail tickets, however you are welcome to pick up your tickets by showing photo identification at our Box Office any time prior to your show. Our Box Office can also e-mail you your purchased tickets to print at your convenience. (Be advised most promotional tickets must be picked up at the Box Office window with the promotional materials in exchange for admission tickets, therefore cannot be e-mailed). You can always add your mobile tickets to your cell phone / passport and present it at the door!

Yes. We accept all major credit cards through our Box Office & in our showroom, including Visa, Mastercard, Discover, and American Express.

We are handicap accessible. If these accommodations are needed we ask that you please notify the Box Office in advance so we can arrange for a reasonable accommodation.

Yes. Comedy is subjective and certain comedians are not for everybody. We do our best to include videos & up-to-date information about the comedian on our website. We recommend watching clips of past performances on YouTube and reading the headliner’s biography to gain insight on the expected performance.

Taking photographs, filming, videotaping, or other recording of shows without the consent of the club and the artist is strictly prohibited. Patrons who abuse this policy will be ejected immediately. We do occasionally offer the opportunity for “Meet and Greets” with the performers after the show. Patrons participating in this are welcome to take pictures during that time.

Please feel free to contact our Box Office at (909) 484-5411 or for more information. We look forward to seeing you at a show soon!

We do have a Group Party Reservation Service for parties of 10 guests or more. Contact our Sales Manager at for additional information and requirements. For group sales incentives, all tickets must be purchased under the same transaction.

Yes, we are a full service restaurant. Check out our CLUB FOOD & DRINK MENU pages for more information.

The majority of seating is done on a first come, first sat basis. We do, however, offer PREFERRED or RESERVED seating if doing a GROUP PACKAGE or VIP PACKAGE. We typically seat the room from the front to the back. The majority of the tables in the showroom seat 4 per table.  We do have a limited number of bench style seating where we typically seat 4-5 people.  We are capable of accommodating large parties through our Event Coordinator; just inquire through our website in advance. We do ask that you arrive early in order to guarantee optimal seating arrangements. You may view our seating chart and take a virtual tour of our showroom on our website.

Arrangements can be made via the Event Coordinator with a GROUP PACKAGE or VIP PACKAGE to have PREFERRED or RESERVED seating.

For our earlier shows we typically offer the option to make a dinner reservation, however this is not the same thing as “reserved” or “VIP” seating. There is no additional cost for dinner reservations and this allows you to enter our showroom for dinner beginning 90 minutes prior to show time instead of the 45 minutes allowed with General Admission. Please note this when purchasing your tickets online or contact our Box Office if you would like to add or remove this to your admission tickets.

The items you purchase during your dinner count towards the two-item minimum per person requirement. The two-item minimum can be food, beverages, or a combination of both. Also keep in mind for most “Special Engagement” shows there may be VIP dinner packages or other options through our Event Coordinator.

Your table and server during your dinner reservation remains the same throughout the entire show.

We do our best to offer a variety of options on our regular menu that accommodate various diets & food allergies.

We love hearing about your experience. Please feel free to write any comments on the comment cards, which are located on your table inside the showroom. You can also email us at

No. Any food item or beverage (with or without alcohol) counts towards the two-item minimum. We offer a variety of non-alcoholic beverages for our underage and non-alcohol consuming customers. We also offer souvenir items such as glassware and t-shirts. Take a tour of our CLUB FOOD & DRINK MENU and we guarantee you will find something to your liking.

Must have a ticket to gain admission to our showroom.

Our experienced mixologists are always ready to make your drink of choice with options on top shelf liquors. Check out our FOOD & DRINK MENU for more information on the variety of specialty drinks we offer as well.

We are always looking for new & experienced talent (cooks, bussers, hosts, servers, bartenders, etc.) and encourage you to come down to submit a resume & fill out an application. We have open interviews every Thursday from 4-5pm. No appointment is needed. 

Please contact the Box Office at (909) 484-5411 for more information.

The showroom is sat front to back. If sitting up front is important to you, arrive early. Many times we have prepaid groups that have paid extra for the front row experience. Sitting in the front, you may be just as much a part of the show as the comic on stage. Most of the time this is not the case. Comics generally have a set and perform that set as planned. However, many comics work with the crowd. In those cases, buckle up, you’re at a live performance, enjoy yourself and leave the judgment outside. Nothing but good times allowed at The Improv. We will always offer you the best seat available. Our small intimate venues don’t necessarily have a “bad” seat.
