Ok, I think I put 'Tuesday' instead of 'Thursday'...not sure what I was thinking...
11am at Starbucks, Kreuzplatz. Kreuzplatz is one stop from Stadelhofen train station - that should be easy to get to from Opfikon, Dietikon or wherever...
If that works for you, please send me a PM with a suggestion of which Thursdays in the next 6 weeks and when I have a couple of people interested, I'll make an event on the forum social calendar.
