Kimchi Family - I'm not sure where it's set, exactly, but most of the story takes place at a traditional Korean restaurant nestled up against the mountains, amidst beautiful scenery seemingly in the middle of nowhere. While it may not be to everyone's taste (due to the sometimes slower pacing), I found it charming, sweet and the characters delightful (and yes, there still is a plot, involving an ex-gangster, as well as a romance.) I wrote a review of it on this site (apparently the literal Korean name is "Fermentation Family" so that's what you'll find it under.)
Gourmet - Sadly underrated, but absolutely my favorite (okay, second favorite!) drama of all time. (Kim Rae Won is so excellent as the male lead!) Some of the story initially takes place at (like the previous one I mentioned) a traditional Korean restaurant which appears to be far removed from Seoul, but you also get to see lots of countryside, woods, and lovely seaside towns, as the main character travels around the country having numerous adventures that all center around food and the theme of how it brings people together. Lots of sibling rivalry, as well as the age-old conflict between older and younger generations. And, yes, a romance that isn't front and center, but I found pretty cute, nonetheless.
Do Do Sol Sol La La Sol - this takes place in the fictional small town of Eunpo, a seaside town. I just have to say, this one is very quirky (some of the characters are even quirkier than the ones found in Hometown Cha Cha Cha.) The main character is rather an airhead, although very kind hearted and determined. Overall it was a fun watch; main disappointment was the last episode which had one of those "whaaa?" kind of endings where you're kind of confused about what the script writers did at the end.
