Phabricator's issue tracker is also an excellent choice over GitHub's simplistic issue tracker.
Also, Gerrit isn't that hard and I've seen small teams get productive with it within a 1-2 weeks.
No need to reinvent the wheel!
By the way: I live in Europe and I haven't worked for one single company which would allow their developers to host proprietary source code with a third party SaaS provider.
Phabricator is nice, but it's more of a full-featured replacement for GitHub as a whole. Some people want to keep most of GitHub and just improve on the code review aspects.

Fair enough, companies vary widely in their acceptance of SaaS -- though Reviewable has plenty of European customers too. But to clarify, neither Review Ninja nor Reviewable (not sure about Omniref) actually host code themselves: they just access it through GitHub APIs without storing it. You can also deploy Review Ninja (and soon Reviewable) on-premises, though of course that means you're on the hook for administrating the system again.

That's the nice thing about Phabricator, you can switch off all features you don't need, and it integrates with GitHub. You can definitely use it just for code reviews, with users logging in using their GitHub accounts and the repositories being hosted by GitHub.

That would work! Third party SaaS probably includes Github.
