I just got back from tonight's performance, I'm surprised so few people here have seen it.
Anyway, I really liked it, it is very funny, with great performances all around. The first act is a little lighter, but it pays off in the second one. The premise is not groundbreaking but the dialogue is sharp, I love the dry humor, very much in the same vein as The Lyons, which I loved.
Highly recommended, well worth seeing.
