I worked at a company that started having code reviews. We started off by just "presenting" code to the team. The team would point out any thing that looked like a bug or areas that required extra QA effort. Just knowing you would have to present your code was enough to increase code quality. We didn't worry about style/best practices/subjective feedback at the beginning. Over a few months we all became more comfortable receiving and giving feedback and that's when we started to solidify the style guidelines. Also our ability to catch bugs without QA cycles helped increase buy-in for code reviews.
