Sunday and Monday nightlife

I am in town for work, my nights are mostly free. After an early dinner tonight and tomorrow I am keen to just roam, drink, get a bit 'loose'... I'm 37/m from Australia... despite my attempts, my French doesn't extend beyond greetings... I try... but I struggle. And it hits at the confidence. Keen to just find somewhere accessible (ny "accessible" I mean no questions asked about a guy on his own that doesn't speak French) and it's fine if touristy; I'll get plenty of local insights from Paris based colleagues during the week.

I am staying near Lamarck but can find my way around...don't mind where it is. Thanks in advance :)
