Cypher does not use ANTLR or similar separate external DSL system. Instead it has it's own parser DSL written in scala, and this is embedded deep within the cypher compiler codebase. The 'grammar file' as such then does not exist, except as a large number of parser rules written in a scala DSL created for this purpose. You can, of course, browse the code and read it for yourself.
