The film centres around a Will-they won't-they romance. Wealthy Jack Cromwell from Long Island runs off to New York City on account of his fiancee's relentless flirting. He attends an Independence Dayblock party where Molly Carr, from Yorkville, Manhattan, falls in love with him. Comic relief is provided by grocer Eric Swenson, above whose shop Molly and her flatmate, Bea Nichols, live. Gaynor performs a charming singing and dancing version of the song " Sunny Side Up" for a crowd of her neighbors, complete with top hat and cane. Later in the film, a lavish pre-Code dance sequence for the song "Turn on the Heat", including scantily clad and gyrating island women enticing bananas on trees to abruptly grow and stiffen, with the graphic metaphor lost on no one, occurs without Gaynor's participation.

Reception
The Times and The New York Times both express the opinion that the film, and the singing voices of Gaynor and Farrell, are all tolerable if not exactly worthy of praise. Despite the sugary sentimentality, the film is engaging, while the cinematography and special effects are impressive. Footage from Sunny Side Up was included in the comedy filmIt Came from Hollywood, which parodied B movies. The film is recognized by American Film Institute in these lists:
Several times throughout the film Gaynor sings the tune "I'm a Dreamer, Aren't We All?" and, on one occasion, sings it impressively, according to the New York Times. The credits are: words, De Sylva & Brown; music, Ray Henderson. The song was punned by the Marx Brothers in the film Animal Crackers. Groucho asks his brother to "play the song about Montreal". Chico asks, "Montreal?, and Groucho replies, "I'm a dreamer, Montreal." The pun has been much-recycled not least in Stewart Parker's award-winning play I’m a Dreamer, Montreal. An early popular recording was by Paul Whiteman and His Orchestra on October 16, 1929 with a vocal group including Bing Crosby and this reached the charts in 1929. The tune was also recorded by John Coltrane in 1958 and included on his album Bahia.
"Turn on the Heat"
In addition to appearing in the Sunny Side Up, "Turn on the Heat" was recorded as a solo stride piano piece by Fats Waller in 1929, and this recording has been reissued numerous times. The song was also used in the 1933 Pooch the Pup cartoon Hot and Cold.
