Excellent use of the space. Three of Spades is a great location for shows that benefit from creative staging.
What I didn't like
The incongruous musical number in the middle only adds to the pacing problem.
My overall impression
What makes witticisms work is a light, deft touch. Sadly, the actors took a sledgehammer to every one, assuming the audience too slow to notice otherwise. As a result, the pacing was too ponderous.
