HI,
You may want to read these
tips on event planning. It is our experience setting a date, time and location gets far more play than asking for meet-up suggestions.
Why not read through posts here to find out what people are talking about in ( oops Wicker Park) Bucktown. Especially if there are largely glowing reviews, you will find people who will want to try it with you.
It's ironic a chowhound suggestion brought you here. We largely left because we could not do event planning without our posts getting pulled. Certainly it wasn't the only issue, however it was certainly a leading contributor.
Good luck! Ask questions here or PM if you need more help.
Regards,
