I am interested in meeting new people in nearby cafes (e.g. Starbucks in Glatt or close around it). Let me know if you are keen.

Why not make a social event? Go to the calendar and set a date: that way others can see where, when, who etc and it generates a bit of 'buzz'. The worst that can happen is nobody can make it, whereby you just re-schedule.

Even if it's for Mothers only...
