I haven't taken any Dutch lessons yet, but my first thought was still "men". Maybe because of German? :P But luckily I quickly remembered they put -en at the end in Swedish. :)
Native. No, there should be no trace of any 'L' here. (And i cant hear it either :-) )
I guess it is the voice's transgression from 'n' to 'e' which might induce this slight 'L'-sound.
