Visiting Marseille - insider tips?

Hi, am visiting Marseille over Easter and would love to hear any recommendations for places to see, bars/cafes/restos etc. Would love to attend an Internations event as well, but there seems to be nothing scheduled so far. Maybe someone would like to meet for a coffee and do a language tandem French/English/German? My French (level B2) needs some practise again. :-)
Cheers,
Leena
