"file.bar: file.foo" dependency is already handled by the "%.bar: %.foo" rule …

Yep, that's what the pattern there is for … ;-)

Not sure what you mean by "any *.foo" file in the line
above … But, taking your example, I will assume you want
anotherfile.bar to be built using the command from the pattern
rule, even though there is no match, and
that any .bar file can be built from file.foo. In
that case, how about:
%.bar: file.foo
cat $< >$@
#file.bar: file.foo
file.foo:
touch file.foo
#file2.bar:
#anotherfile.bar: file.foo
