C'est si bon (film)

C'est si bon is a 2015 South Korean musical drama film written and directed by Kim Hyun-seok. It was released on February 5, 2015.

C'est si bon (French for "It's so good") was an acoustic music lounge located in Mugyo-dong, Seoul. During the 1960s and 1970s, the venue was very popular with Koreans in their twenties and thirties, who went there to listen to live music. Among the bands known for having played there was the folk music duo Twin Folio composed of Yoon Hyung-joo and Song Chang-sik; this film depicts the band's beginnings while including a fictional third member, Oh Geun-tae.

Plot
In the late 1960s, C'est si bon is the music lounge every unknown acoustic band dreams of playing. It is where Geun-tae, a naïve country boy, meets musical prodigies and rivals Hyung-joo and Chang-sik. Together they form a band and name themselves after the iconic venue — the C'est si bon Trio. As the three young musicians bicker over their music, beautiful socialite Ja-young enters the picture and becomes their muse, launching a series of moving love songs. Ja-young falls for the pure-hearted Geun-tae, but they part ways when she accepts a once-in-lifetime shot at an acting career. 20 years later in the 1990s, Geun-tae and Ja-young meet again.
