The main focus of the story is definitely food, so I wouldn't recommend diving into the story specifically looking for romance, ecchi or any dramatic plot. It's simply 89 chapters of Yakumo making food for Yamato.
I binged the whole series in one night and I still go back to it and choose a random chapter to reread purely because every chapter is so comforting. The way that Yakumo is portrayed is so endearing, it just makes me want to sit down and listen to her talk for hours. There is never a moment where she is written in a way that is disrespectful to her character or backstory. The food that she makes for Yamato always looks so good and the way that Yamoto enjoys eating everything is so satisfying - it's almost like watching a mukbang video. I really love the way the author draws the characters' expressions and gestures so genuinely. The interactions between the two characters are just so funny, adorable and cringeworthy, which just makes the story even more loveable.
While the story eludes to an age gap relationship in the story, it's very innocent and written in a way that is tasteful and not sexualised. That being said, the author does sometimes draw pin-ups of Yakumo for the chapter titles lol.
As for any cons I will agree with MagicMaterwelon that the story could have explored Yakumo's backstory and emotions more relating to her becoming a widow, or even expanding on Yamato's childhood further to flesh out how and why he developed his independent character trait.
All in all, would highly recommend for an easy, no commitment, light read.
