"The supporting actors do an admirable job in multiple roles, especially the hilarious and adorable Sebastian, who plays Heather’s roommate, a secretary, and Porter’s ex-wife."

"The show's standout performer, however, is Maureen Sebastian. She tackles three seemingly stock characters -- Porter's obnoxious ex-wife Carlotta, Heather's meek secretary Wendy, and especially, Heather's too-chirpy lesbian roommate Claire -- and delivers each with truly consummate flair, stealing scene after scene."

"The shining star of this adventure is Sebastian as the sexually vibrant but emotionally distant Tong. In both her on-again, off-again rapport with Quang and her pitched battles with her mother ... Sebastian injects this show with a compelling immediacy."

"Plunkett and Sebastian have both shined in previous roles, but those performances gave no indication of the level of talent they display here. Both actors take Mensch's multilayered and detailed script ... and elevate it to another level."

"Plunkett and Sebastian give superb performances, mining the text for every possible joke, at times even surpassing the material (Sebastian in particular demonstrates impeccable comic timing)."

"...it’s [Maureen's] portrayal of Margie proper that really gives the play its depth. A little bit crazy, a little bit sad, a little bit desperate, Margie careens from extreme to extreme... Sebastian’s portrayal is so volatile that we’re not sure whether she’ll pull it out until the end of the show."

"This play benefits from some fine performances, including Maureen Sebastian’s as the giggly Upper East Sider Josephine."
