Barefoot in the Park by Neil Simon
Corrie and Paul are newly-weds who have just moved into their cold eyrie apartment in New York. Corrie is starry-eyed, Paul less so after staggering up 5 flights.
Their house seems to be populated by unusual people, the most bohemian being Victor whom Corrie finds entertaining. Corrie tries matchmaking between Victor and her lonely mother with a disastrous dinner.
