- PGPat GablerSep 6, 20265.0Enjoyed dinner, and a short life/financial planning presentation. Then we were treated to a magician and a comedian. All hosted by the Miles Financial Group. Overall an exceptional evening.
- SPstacy phillipsAug 29, 20265.0Saw Deray Davis funny as hell. Love this place seen amazing comedians here, Decent food as well ty for the continued laughs....
- KJKathy JAug 26, 20263.0Enjoyed the comedian we went to see (Joe Machi) We did not enjoy the vulgar trailers they played of shows that were coming up. Nor did we enjoy the food or drinks (2 drink or food minimum per person) But since we only went there to see Joe Machi, his routine was totally worth it!
- JJJohnnyAug 24, 20261.0It’s hard because I want to support this Improv location because I’ve seen so many good shows, especially last night August 22nd. The service is absolutely terrible. Definitely not ADA welcoming. Drinks were mediocre at best. We all should have just got beer 🤷🏽♂️
- UMUlielax MentatAug 23, 20262.0Story short. 8/22 Arrived an hour And half early and our group of 5 friends were split up in tables of two up in the very front to the stage with half of the group not facing each other. Asked early if we can go to a booth. Keep In mind, with 95% open capacity , we were given an excuse that they need to keep everyone compact due to a smaller turnout. Supervisor told us he would consider it when doors closed. Never followed up despite the venue becoming half full with larger group tables available prior. Comedians 5 stars and management 2 stars in service experience.
