It's the cafe owned by the mother of big K-pop Star, Miss A Suzy. Suzy’s mother used to run a small Korean snack bar but after Suzy earned enough money, she set up a nice cozy cafe for her mother.
Cafe Soo is located in Gwangju, Suzy's hometown. If you're trying to visit from Seoul, it would be a long journey but if you're a big fan of Suzy, it's worth the travel. Gwangju is also a nice city to visit in Jeollanam-do province. It used to be a Korean snack joint, but it changed to a cafe after Suzy got popular. Basically everything is covered up with Suzy's pictures from the entrance that you walk in. The general price of the cafe is pretty inexpensive than the usual coffee prices.
