- MSMel SJul 19, 20265.0Arnez J tonight!!! Too funny 😂😂😂🩷
- DGDaniel GuerraJul 13, 20265.0Love coming here, I've been here at least 20 times and will continue to enjoy shows here. !
- SDSherina DelgadoJul 6, 20264.0I've been here about 3 times. Service is amazing the servers are so nice and attentive. The most recent time for craig conant which was hilarious btw. Atmosphere is awesome the only complaint i have is the seating. I think stadium seating would be better than the table seating. If theres 4 ppl to a table you have to turn your chair around and have your legs and feet in the walkway with the servers walking in and out and people walking back and forth to the restroom and their seats. Its pretty squished in there but it is a tiny establishment. I think stadium seating would fix this issue though or pod seating for couples. Other than that i love the improv experience!
- RUR. U.Jun 27, 20265.0Servers are always great and attentive. You can also order through their app by scanning the QR code on your table. Every table is close enough to see the act clearly. If the bathroom is too full after the show, you can just go use the one in the mall. Plenty of things to do in the mall if you get there too early before the show.
