I actually really like this show. I'm not going to claim it's a particularly *good* show by any means, but it is very pleasant to watch.
It's got a very calm, gentle atmosphere about it, a sort of warm mellow quality that I really enjoyed.
The plot is paper-thin, but the characters are charming and believable to the point where the actual story almost doesn't matter - you just want to keep watching these people living their lives.
The story could have explored alcoholism and Korean drinking culture and it is indeed disappointing that it fails to live up to that potential (oh the things that could have been).
Personally though, once I lowered my expectations a bit, found a lot to like about the series just as it is. The friendships depicted are wonderful, the humour is often understated but works very well with the story, and the pacing and relationship progression are absolutely perfect.
There is no huge drama, no pre-finale curse, there's honestly barely any conflict at all. I can understand why a lot of people lost interest in the show because of this, but I find it a refreshingly realistic take on a budding relationship that makes for a good palate cleanser from more intense dramas.
If you're interested in a low-angst, slice-of-life type drama about people appreciating good food and good company, which features a very wholesome, gentle slow-burn romance, then I'd recommend giving this series a shot.
