At a medium sized company. Everything gets code reviewed by one or two teams. Only one or two approvals are required. Stash/bitbucket is used and we leverage the Default Reviewers feature. The process works very well, is integrated with our ticketing system (Jira) and build system (Bamboo). We are nice in the code reviews but thorough and a little pedantic about style. The only reason I can picture not doing code review is if there is only one developer. It is an excellent way for everyone to learn, reduce bugs, reduce spaghetti code, force you to write tests, etc.
