The Sims 4: Cool Kitchen Stuff Review (Nysari)
It's fine. Mostly upvoting it to counteract how negatively it's been reviewed so far.
Like any stuff pack, it's one of the cheaper types of DLCs to add some extra play items, build items, and CAS items. This is actually the sort of DLC I'm personally okay with, as the game is definitely complete without it -- it just adds some fun extra stuff if you happen to pick this up on sale or as part of a bundle.
I mostly picked this up because of the ice cream maker, specifically because the flavor "Taste of Diet" can be eaten by children and toddlers and will make them lose weight. I always felt a bit unfairly punished for failing to intervene when my sims (or the butler/nanny) feed my toddlers quick food, so it's nice to have a less-cheaty-than-cheating reset. It also works well to counteract the weight they'll gain if they eat a lot of ice cream. The kitchen stuff and CAS items are a fun added bonus to ease the sting of paying 7 bucks to assuage the body image issues I project onto my child sims.
I will say that I dislike that sims will put the finished ice cream in their inventory instead of automatically serving it (like any other food). I suppose it stops them from just deciding to make and eat ice cream whenever they want, but that's really my only gripe.
