I'm only on episode 4 of "Dine with love", but it reminds me of "Dating in the kitchen" because:
- Female protagonists good at cooking, with sweet, kindhearted personalities.
- Male protagonists in the roles as CEOs who have "closed off their hearts".

Both shows also has a focus on food and the importance it can have in our lives.

In many ways these are not that similar, but for me they both left me with a lasting impression. They are both strong historical dramas, depicting love and sorrow, hardships of war, spanning over longer periods of time.

Similarities:
Debt-ridden, and desperate life situations pushes main character into contract relationship.

I would say "Marriage Contract" is heavier (emotionally) to watch than "Man in Love".

Different genre, but for me these two have some similarities when it comes to the vibe they give.
As I wrote in my review for My Sweet Mobster, it is kind of like the scriptwriters didn't take themselves too seriously, which resulted in some lighthearted humor.
Both of these shows also showcases underlying issues; for MSM it is ex-convicts' struggles to get back into society, and for KF it is widows' status during Joseon times.

If you are a foodie, both of these series have a lot of food related scenes.
Other than that, Chocolate is likely to make you emotional and maybe cry, whereas Dating in the Kitchen has more "run of the mill" plots in the script, and will likely leave you with a more "warm, fuzzy feeling".

Both are coming of age-dramas, quite easy on the mind (comfort-dramas), following a group of friends, and with a somewhat awkward female protagonist.

Coming of age, school-drama, finding love, transitioning into adulthood and friendship.
Slow-paced, no extremely vicious people, although there are elements bringing dynamics to the story.

Mature career women in a workplace setting, tackling obstacles both at work and in life, and finding love without looking for it.

Stand or Fall follows the female protagonist and her two friends, whereas The Rational Life centers more around only the female protagonist.
In SoF it is "enemies to lovers", in TRL it is opposite age-gap.

Both are "historical romcoms" – funny and charming.
Both have strong female characters, although they are in very different roles.

These two dramas might not appear very similar from the synposises, but they are both a mix of workplace/mature relationship dramas with strong female characters.

Where "Sunshine of my life" revolves mostly around the main protagonist, "Stand or Fall" also follows the storylines of her two friends.

Both are what I like to call "healing dramas"; overcoming something, or finding a new path in life.
You connect with the characters, and avoid the extremes from plotting and scheming.

Some of the similarities are independent, confident career women, not plot-heavy or too extreme scheming characters, but rather depicting a more recognisable character gallery and situations that seem more plausible.
Both stories also contains something around how events during childhood can effect a person.
