A lot of other examples given in other comments are quite the opposite. Clever code in long functions with single character variable names. Chromium shines in consistent naming, structure without much overelaborate uses of design patterns and general aim for maintainability and readability. I'm not saying there aren't those things in Chromium too (I've seen them), but they are well contained.
I've also seen a talk at CppCon (2019 I think) that spoke somewhat negatively about the code base. Can't find the reference, sorry.
