Goo Dae Young has fallen into a slump in his thirties. In order to heal his wounds, he embarks on a journey to revisit the food that he loved in his twenties with former college classmate Lee Ji Woo, and the two not only share their meals but also relive their memories of the past.

The second season follows Yoon Doo Joon's character as he moves to a new building and reunites with his grade school classmate Seo Hyun Jin. She's been living alone for ten years, which means she'll have plenty of her own single-living tips and opinions about food, setting her up to have a contentious relationship with Yoon Doo Joon.

She's a freelance writer with a crush on her other neighbor. He's a civil servant who lives simply and eats simply. The sequel comes from the same PD-writer team that brought us the first season, and promises another round of neighborly hijinks and, of course, lots and lots of food.

Let's Eat depicts the daily life and romance of a single woman and a murder case occurs in her neighborhood. Lee Soo-Kyung is a 33-year-old single woman. She divorced when she was in her 20's and now lives alone. She always wants to carry herself with dignity, but she loses self-control when she is near gourmet foods. Koo Dae-Young is a gourmet, especially talented with describing the taste of foods. He often lies when he opens his mouth, but he is usually considerate to others.
