I can also join. Just willing to meet a few non office people around office . I am fine on anyday generally and for this week I would go with the majority, friday looks good to me.
both weeks are fine with me - actually next week is even better, since i get visitors today and don't know if they want to spend lunch time with me tomorrow...
and about location: the closer to my office the better :-)
again - tram stop (red line 2) kappelli :-)
3 stops from albisriederplatz - i still don't know the area very well, but have never seen a migros around there... so i assume it IS pretty far from you...
