Your first sentence is awkward. I'd say 어제 영화관에서 영화를 봤는데 재미있었습니다. Or if the fact of the movie being fun is the reason you watched it, you'd say, 그 영화가 재미있다고 해서 어제 영화관에 가서 봤습니다. And still the more if you find any movie interesting, and thus went out to see a movie yesterday, it'd be 영화가 재미있어서 어제 영화관에 가서 영화를 봤습니다. The second one is fine, although I'd hesitate on using 요리하다 with 김치. The use of 그리고 is very natural here as it means 'and then'. Just a side note: You don't cook 김치 like other food, and by that I mean 요리하다 has a nuance of cooking with skill, usually to prepare something that will be eatten a while afterward, while you don't just cook up 김치 and eat it. You make tons of it and store it in the fridge (or under the ground, if you prefer the old way). We have another verb for this continuum of grueling tasks of salting the cabbages, putting the spices in between them, etc. it's 담그다.
